When I used to write for @osnews in the early 2000s, I was a proponent of the BSD-like licenses, where a user could decide not to open source back their changes. I still believe in that freedom, but I don't believe in all people anymore: corporations now have reached total #enshittification, so now I'm a believer of the AGPL, the most extreme version of the GPL3. Everything should be as open as possible, and remain so. No exceptions.
