I am puzzled by Section 3.1 of the Weak 2.3 license. Can a Licensor
choose what license will be used for their distribution? If I receive
code under the ESA-PL Weak Copyleft license, can I sublicense it under
the GPLv3? If that's true, doesn't that mean that every Contribution was
licensed under at least four licenses, the ESA-PL Weak, ESA-PL Strong,
GPLv2 (and later versions) and CeCill v2 (and later versions)?
In Section 3.2.1 of the Weak and Strong licenses you use the term
"extensions of the Software." How will the word "extensions" be
interpreted? When is something an "extension of the Software" and not an
External Modules or System Libraries? Is "extension" a legal or software
term of art?
In the same section it's not clear whether "in or on a volume of a
storage or distribution medium" is an additional limitation on "such as
to form a larger program." In other words, if a separate work is
combined with the Software to form a larger program, but it's not in or
on a volume of a storage or distribution medium, does that mean the
license does not apply? (I suspect the wording "in or on a volume of a
storage or distribution medium" is altogether unnecessary).
Thanks,
Pam
