[License-review] ModelGo Attribution License, Version 2.0 FINAL CALL FOR COMMENTS

[Moming Duan]

Hi McCoy and all,


Thank you for the careful review and the structured questions.

On the preamble difference:

There is a difference in the language in the preamble of ModelGo Zero vs ModelGo Attribution. ModelGo Zero specifically points out the Sec 3 disclaimer, but Attribution does not. Also Attribution says that if you don't agree to the terms, then no rights are granted; ModelGo Zero doesn't require this. Is there a reason for that discrepancy between licenses? Should they be synchronized in this section of the license to be identical?

When we removed the condition from Zero, the preamble was adjusted accordingly: MG0 has no obligations, so its acceptance clause only asks the user to read and understand the license (pointing to the Section 3 disclaimer); MG-BY carries attribution obligations, so it keeps the "agree to be bound" structure.


About Q1-Q4: for the community's reference, here is the relevant background from ModelGo review threads:

Q1 (hosted/API distribution and Freedom Zero):

  *   Moming, Feb 2025: the submission identified the chatbot/remote-access scenario as a design target [2]
  *   Josh, Feb 2025: flagged the AGPL-style nature of the hosted/API licensing [3]
  *   Yokoi-san, Sep 2026: asked how the Section 2.2(a) conditions operate for hosted-only deployments; the steward's follow-up confirmed the reading [4][5]

Q2 (Model + Complementary Materials in one definition):

  *   Pam, Mar 2025: raised the "collectively" vs "and/or" question [6]
  *   Moming, Mar 2025: clarified the intent [7]
  *   Josh, Feb 2025: asked for expert review of the definition [3]
  *   Moming, Jul 2025: tightened the definition [8]

Q3 (termination directed only at the Licensor; patent claim terminating the copyright grant):

  *   McCoy, May 2025: concluded "not an OSD violation, but an uptake issue" [9]
  *   Moming, Jun 2025: the automatic-termination change [10]
  *   OpenMDW thread, Aug-Sep 2026: precedents for patent claims terminating copyright grants [11]; Yokoi-san's three-axis framing [12]

Q4 (the Derivative Materials trigger):

  *   McCoy, May 2025: first raised the overbreadth concern (the "Liberty or Death" reading) [9]
  *   Moming, May 2025: responded on "patent trap" and uptake grounds [1]
  *   Moming, Dec 2025: excluded distillation-based models from Derivative Materials [13]
  *
McCoy, Sep 2026: contrasted MG-BY with OpenMDW-1.1 [14]

Should the community have additional questions on these matters, I am happy to provide further clarification.


Best,
Moming
