* Jacob Bachmeyer: > is the SSPL actually derived from the AGPL?
Yes, it is. > If so, does the SSPL itself infringe the FSF's copyright on the GPL > license text? Yes, but the FSF has given a wide-ranging permission to create and distribute derivative works of the GPL itself: | Can I modify the GPL and make a modified license? | | It is possible to make modified versions of the GPL, but it tends | to have practical consequences. | | You can legally use the GPL terms (possibly modified) in another | license provided that you call your license by another name and | do not include the GPL preamble, and provided you modify the | instructions-for-use at the end enough to make it clearly | different in wording and not mention GNU (though the actual | procedure you describe may be similar). | | If you want to use our preamble in a modified license, please | write to <licens...@gnu.org> for permission. For this purpose we | would want to check the actual license requirements to see if we | approve of them. | | Although we will not raise legal objections to your making a | modified license in this way, we hope you will think twice and | not do it. Such a modified license is almost certainly | incompatible with the GNU GPL, and that incompatibility blocks | useful combinations of modules. The mere proliferation of | different free software licenses is a burden in and of itself. | | Rather than modifying the GPL, please use the exception | mechanism offered by GPL version 3. <https://www.gnu.org/licenses/gpl-faq.html#ModifyGPL> I think this is clear enough, and it overrides the terms at the start of the GPL.
