“Google and Yahoo are among the largest users of free
software. Under previous GPL terms they could adapt this software
for their own use and commercialize it, and users would have rights
to the source code only when running the software residing on their
systems. The AGPL has an additional paragraph, “Remote Network
Interaction; Use with the GNU General Public License,” that gives
users rights to remote source code as well.“This licensing has been an ongoing discussion at Debian,
including in wishlist bug reports. The Debian project has been
following its own social contract, primarily addressed in the
Debian Free Software Guidelines (DFSG). Debian releases only
software in its Linux distro that falls under these guidelines.
Conflicts arose, for example, around Mozilla’s trademarks on for
Firefox and Thunderbird.”
