[the SSPL] primarily replaces [the AGPL v3’s] section 13 “Remote Network Interaction; Use with the GNU General Public License.” with a new section that requires that anyone who offers the functionality of SSPL-licensed software to third-parties as a service must release the entirety of their source code, including all software, APIs, and other software that would be required for a user to run an instance of the service themselves, under the SSPL. In contrast, the AGPL v3’s section 13 covers only the program itself (the copyrightable work licensed under AGPL v3).
I get what they’re going for and I sympathize with the goal, but I’m not sure there’s any software in the world that could comply with that license because it would have to release an entire container or disc image with nothing but SSPL software from the kernel on up. Does a SSPL-licensed kernel or httpd even exist?
