> But this means that it is impossible for the GPL to restrict any action which you would have been legally authorized to do even if the software had not been licenced under any licence.
how would this statement be affected by French Law?
This is an actual interested question and not HN know-it-all being aggressive and trying to claim you're wrong (figured I should say it)
Section 13 of the AGPL which is the one the author says is ineffective starts:
"Notwithstanding any other provision of this License, if you modify the Program, your modified version must ..."
The obligation starts from "modification" of the software, and modification of software is an act protected under copyright law. Hence you need an authorisation for it (without prejudice to fair use and copyright exceptions of course).
You develop X and distribute it to B.
B modifies X (becomes X.1) and because B has been well advised by lawyers, B knows that modification of software is an act restricted under copyright law, and so B went to go read the LICENSE file and found Section 13 of AGPL. As a result because he/she is diligent, B ensures that the source code of X.1 can be accessed by putting a link to a server in X.1's user interface.
See Section 13 of AGPL:
B's "modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge ..."
B distributes X.1 to C
C runs X.1 which is a version that already offers all users a way to get the source code.
That is, contract the development to a third party. Let's say A wants proprietary modifications to an AGPL product (X). A contracts B, a solutions provider to make the changes. B is legally required to provide the changes to their X.1 product to anyone that uses it. However, only A is their direct user. Now since A did not modify X to X.1 they are not required to provide a direct download link in the application to the sources for X.1
I'm unsure if GPL style protections still apply and I as a user can request the sources from A by making an explicit request. (I guess not, since they never shared the application with me, only access to it via the network)
but the distribution requirement in the AGPL should trigger just as well as in the GPL. the only difference is that access through the network is added as a trigger.
so i don't actually believe that the AGPL distribution requirement only triggers on modifications. it should trigger on unmodified versions too, just like the GPL. whoever provides the program, is required to provide the source.
this certainly was the intent, and if the AGPL does not implement that intent then that would be a major flaw, which i can't believe they would allow to slip through when designing the license
Take for example the DeHackEd Doom patch editor for old-school DOS Doom, which patched the Doom.exe binary to change player speed, enemy behavior, text messages, etc. in ways that WADs alone couldn't. You are free under copyright law to use DeHackEd to patch your own binary, and to distribute your patches so others may use DeHackEd to apply them, but not to distribute patched Doom binaries.
The same holds true for any game mod, really, and even those Windows installer editors which produce stripped down versions of Windows (like 98lite or the more recent Mini11).
I mean come on. The entire point of the AGPL is to make the GPL apply even in the absence of distributing anything.
