<html><body><div style="font-family: arial,helvetica,sans-serif; font-size: 12pt; color: #000000"><div>If I understand correctly, the main difference with MPL is the avoidance of the license compatibility of the license.</div><div><br data-mce-bogus="1"></div><div>While I believe that the license compatibility is indeed a good feature of the MPL that makes it one of the most viable licenses in the file-level copyleft realm, and possibly the best, this is obviously a matter of personal preference and my disagreement with the criticism should not fetter the discussion of the technical choice.</div><div><br data-mce-bogus="1"></div><div>May I point out, however, that the license compatibility can be opted out, removing at least in part the rationale for putting forward this license. Admittedly, the way the opt out is done is not clear and I have seen bad and confusing strict uses that required interaction with the owner of the project, but this is more a matter of poor use of the licensing statement than a flaw of MPL.</div><div><br data-mce-bogus="1"></div><div>Therefore, I believe this license scores negative points in terms of proliferation. See also the remarks in the last paragraph.</div><div><br data-mce-bogus="1"></div><div>Coming to a technical analysis, while by substantially reusing MPL would lessen the burden of reviewing any single sintagma of the license, I am not sure 10.1-10.3 is legit. In the original version, OK, but I think you should retain the original disclaimer of Mozilla (the author and ostensibly copyright holder of the license) and if anything *add* a requirement to distinguish from your derivative version of the license, by claiming -- I guess -- some kind of trademark protection over the name to avoid confusion. This would be consistent with 10.3 of the MPL. I would check with them they are ok with it. </div><div><br data-mce-bogus="1"></div><div>This is exactly one of the things a lawyer would probably have noticed as deserving more attention. </div><div><br data-mce-bogus="1"></div><div>Also, I am personally not impressed by the idea that someone offers a new license not for using it as copyright holder, but just to offer a new variant or license in case some projects wanted and have been advised to adopt it. Until there is some appetite by actual projects, submitting it appears to be nothing but an intellectual exercise, not meeting the bar for eliciting the attention of OSI and approve it. I would welcome contrarian arguments.</div><div><br data-mce-bogus="1"></div><div>Cheers </div><div><br data-mce-bogus="1"></div><div>Carlo</div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div><br></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><blockquote style="border-left:2px solid #1010FF;margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>Da: </b>"Loncothad" <me@loncothad.cc><br><b>A: </b>"license-review@lists.opensource.org" <license-review@lists.opensource.org><br><b>Inviato: </b>Marted́, 27 maggio 2025 0:57:37<br><b>Oggetto: </b>[License-review] Request for OSI Approval: Tiwaz License, version 1.0 (New License)<br></blockquote></div><div data-marker="__QUOTED_TEXT__"><blockquote style="border-left:2px solid #1010FF;margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><div dir="auto" style="font-family: verdana; font-size: 14px;"><div style="box-sizing: border-box;">Dear OSI License Review Board,</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">I am writing to request the review and approval of the "Tiwaz License, version 1.0" as a new Open Source Initiative (OSI) approved license. I believe this license aligns with the Open Source Definition and offers a valuable option for the open source community.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">This license comes as a stricter and disambiguated version of the "Mozilla Public License Version 2.0". More info on that in the README of the main repository of the "Tiwaz License, version 1.0" - <a href="https://github.com/tiwaz-license/version-1.0/blob/draft/README.md" id="isPasted" style="box-sizing: border-box; color: rgb(0, 102, 147); text-decoration: underline; user-select: auto;" target="_blank" rel="noopener noreferrer">https://github.com/tiwaz-license/version-1.0/blob/draft/README.md</a>.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">I am contacting you on behalf of the Tiwaz Project as the owner of the domain (https://tiwaz.fyi/, currently empty website) and the GitHub organization (https://github.com/tiwaz-license/).</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">1. License Name:<br style="box-sizing: border-box;">Tiwaz License, version 1.0</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">2. License Text:<br style="box-sizing: border-box;">The full license text can be found at <a href="https://raw.githubusercontent.com/tiwaz-license/version-1.0/refs/heads/draft/LICENSE.txt" style="box-sizing: border-box; color: rgb(0, 102, 147); text-decoration: underline; user-select: auto;" target="_blank" rel="noopener noreferrer">https://raw.githubusercontent.com/tiwaz-license/version-1.0/refs/heads/draft/LICENSE.txt</a>. I'm also attaching it as a LICENSE.txt file in the attachments.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">3. Affirmation of Compliance with the Open Source Definition (OSD):</div><div style="box-sizing: border-box;">The Tiwaz License, version 1.0 complies with the Open Source Definition, as its progenitor, the Mozilla Public License Version 2.0, does.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* It meets OSD 3 (Derived Works): The license explicitly permits modifications and derived works. Section 2.1 grants the right to "modify... its Contributions." Section 3.1 mandates that any distribution of Covered Software, including "Modifications that You create or to which You contribute, must be under the terms of this License." Section 3.2 ensures that if an Executable Form is distributed, its Source Code Form remains available under this License and that terms for the Executable Form do not limit rights to the Source Code Form. </div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* It meets OSD 5 (No Discrimination Against Persons or Groups): The license grants rights universally. The term "You" (Section 1) applies to "an individual or a legal entity exercising rights under this License" without any discrimination based on personal or group characteristics. </div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* It meets OSD 6 (No Discrimination Against Fields of Endeavor): The license does not restrict the use of the software in any specific field. Section 2.1 grants broad rights to "use... and otherwise exploit its Contributions" for any purpose. </div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* It meets OSD 9 (License Must Not Restrict Other Software): The license does not impose restrictions on other software distributed alongside it. Section 3.3 allows You to "create and distribute a Larger Work under terms of Your choice," provided You comply with the Tiwaz License requirements for the "Covered Software" component. A "Larger Work" (Section 1) explicitly combines Covered Software with "other material... that is not Covered Software."</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">4. Projects Currently Using the License</div><div style="box-sizing: border-box;">None as it was created just now because of the drawbacks of the MPL.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">5. License Steward and Submitter Details:</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">5.1. License Steward</div><div style="box-sizing: border-box;">5.1.1. Name: Tiwaz Project</div><div style="box-sizing: border-box;">5.1.2. Contact: <a href="mailto:contact@tiwaz.fyi" style="box-sizing: border-box; color: rgb(0, 102, 147); text-decoration: underline; user-select: auto;" target="_blank" rel="noopener noreferrer">contact@tiwaz.fyi</a> or <a href="https://github.com/tiwaz-license" style="box-sizing: border-box; color: rgb(0, 102, 147); text-decoration: underline; user-select: auto;" target="_blank" rel="noopener noreferrer">https://github.com/tiwaz-license</a><br data-mce-bogus="1"></div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">5.2.

Affilation: None</div><div style="box-sizing: border-box;">5.2.4. Relationship to Steward: Author of the license</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">6. Additional Information for License Review</div><div style="box-sizing: border-box;">The primary motivation for this license is to provide a clear, disambiguated, and version-immutable option for developers, drawing from the robust structure of MPL 2.0 but with distinct policy choices.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">7. Unique Identifiers</div><p id="isPasted" style="box-sizing: border-box; color: rgb(68, 68, 68);">As a new license, it does not yet have an assigned SPDX identifier or a ScanCode identifier. I would be happy to work with SPDX to obtain an identifier upon OSI approval.</p><div style="box-sizing: border-box;">8. Gap Filled by the New License:</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">The Tiwaz License, version 1.0 aims to fill a specific niche for developers seeking:</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* A modern, file-level copyleft license with explicit patent grants and a defensive termination clause, similar in structure to the MPL 2.0.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* Strict version immutability: Unlike licenses that allow distribution under "this version or any later version," (MPL 2.0 allows it too) the Tiwaz License 1.0 (Section 10.2) mandates that software licensed under it must <em style="box-sizing: border-box;">always</em> be distributed under that exact version. This provides absolute predictability of terms for a given piece of software over its entire lifecycle, which some developers and organizations find crucial.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* Simplicity through omission of direct GPL-family compatibility mechanisms: Unlike MPL 2.0, the Tiwaz License 1.0 intentionally omits the "Secondary License" framework. This simplifies the license text and its direct application, creating a different compatibility profile. While Larger Works can still incorporate Tiwaz-licensed code alongside GPL-licensed code (as separate components), the Tiwaz-licensed files themselves do not have a direct path to be relicensed under GPL terms via the license itself.</div><p style="box-sizing: border-box; color: rgb(68, 68, 68);">9. Comparison with Similar OSI-Approved Licenses:</p><div style="box-sizing: border-box;">The most similar OSI-approved license is the Mozilla Public License Version 2.0, which is the progenitor to this license.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">Key differences:</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* Version immutability: Tiwaz License 1.0 mandates distribution only under the originally received version. MPL 2.0 (Section 10.2) permits distribution under the original version or any later version published by the steward. This is the most significant policy difference.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* Tiwaz License 1.0 does not include definitions for "Secondary License" or "Incompatible With Secondary Licenses," nor the associated provisions found in MPL 2.0 (e.g., MPL 2.0 Section 3.3, Exhibit B) that allow MPL 2.0 covered code to be distributed under certain GPL-family licenses when part of a Larger Work. This makes the Tiwaz License 1.0 text simpler in this regard but alters its GPL compatibility characteristics.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* Notices (Section 3.4): The Tiwaz License 1.0 does not include MPL 2.0's explicit clause allowing alteration of notices to remedy known factual inaccuracies. This is a minor difference making Tiwaz 1.0 slightly stricter on notice alteration.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">* Removed Section 2.4 (Subsequent Licenses): Due to the strict version immutability in 10.2, the clause corresponding to MPL 2.0's Section 2.4 (which clarifies contributor obligations if a later license version is chosen) was removed as it became contradictory.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">10. Legal Review</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">The Tiwaz License, version 1.0 was drafted by me based on the already established open source license patterns (specifically MPL 2.0) with specific policy changes. It has not undergone a formal review by legal counsel but given the nature of the license I don't think it is necessary. I welcome the rigorous review process of the OSI and am open to feedback from legal experts.</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">---</div><div style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">I believe the Tiwaz License, version 1.0 meets the requirements for OSI approval and offers a useful, clear, and dependable option for the open source community. I look forward to your feedback and am available to answer any questions you may have. </div><div id="isPasted" style="box-sizing: border-box;"><br style="box-sizing: border-box;"></div><div style="box-sizing: border-box;">P.S.
