l'AGPL, pour prendre la licence libre qui fournit le moins de libertés !?

Tu pourrais élaborer en quoi l'AGPL apporte moins de liberté que la GPL ?

Pour aider, ci-dessous le diff entre les 2 textes de licence, sachant que

• < correspond à la GPL
• > correspond aux ajouts de l'AGPL

Pour moi, l'AGPL ajoute principalement une liberté : celle de proposer la version du logiciel utilisé en SaaS et revenir sur quelques précisions concernant la Tivoisation (qui sont des freins à l'exercice de ses libertés).
Je prends le point de vue de l'utilisateur (et du potentiel développeur souhaitant faire évoluer le logiciel).

< the GNU General Public License is intended to guarantee your freedom
< to share and change all versions of a program--to make sure it remains

< the GNU General Public License for most of our software; it applies
< also to any other work released this way by its authors. You can apply
< it to your programs, too.

< To protect your rights, we need to prevent others from denying you
< these rights or asking you to surrender the rights. Therefore, you
< have certain responsibilities if you distribute copies of the
< software, or if you modify it: responsibilities to respect the freedom
< of others.
< 
< For example, if you distribute copies of such a program, whether
< gratis or for a fee, you must pass on to the recipients the same
< freedoms that you received. You must make sure that they, too, receive
< or can get the source code. And you must show them these terms so they
< know their rights.
< 
< Developers that use the GNU GPL protect your rights with two steps:
< (1) assert copyright on the software, and (2) offer you this License
< giving you legal permission to copy, distribute and/or modify it.
< 
< For the developers' and authors' protection, the GPL clearly explains
< that there is no warranty for this free software. For both users' and
< authors' sake, the GPL requires that modified versions be marked as
< changed, so that their problems will not be attributed erroneously to
< authors of previous versions.
< 
< Some devices are designed to deny users access to install or run
< modified versions of the software inside them, although the
< manufacturer can do so. This is fundamentally incompatible with the
< aim of protecting users' freedom to change the software. The
< systematic pattern of such abuse occurs in the area of products for
< individuals to use, which is precisely where it is most unacceptable.
< Therefore, we have designed this version of the GPL to prohibit the
< practice for those products. If such problems arise substantially in
< other domains, we stand ready to extend this provision to those
< domains in future versions of the GPL, as needed to protect the
< freedom of users.
< 
< Finally, every program is threatened constantly by software patents.
< States should not allow patents to restrict development and use of
< software on general-purpose computers, but in those that do, we wish
< to avoid the special danger that patents applied to a free program
< could make it effectively proprietary. To prevent this, the GPL
< assures that patents cannot be used to render the program non-free.

> incorporate. Many developers of free software are heartened and
