Stallman’s usual take is “Yeah sure you can sell it, as long as you respect the 4 freedoms.”. So I don’t think selling Free Software is against the spirit of FOSS. The issue is rather that the Free Software is against the spirit of selling because realistically you can sell it to one entity which can then just make 7 billion copies of said software. At that point it’s no longer financially viable to sell it for you.
I also think that the majority of people creating Free Software would be fine with someone else selling it. Remember how much permissive-licensed software is out there. If authors really cared, they would have licensed the software under GPL, but instead they even allow it to be used with commercial licensing. Obviously I’m not taking away your opinion, but I don’t think your opinion represents the majority of FOSS.
Ignoring Red Hat which according to the Software Freedom Conservancy organization they GPL violators.
But with Ubuntu it depends on whether you consider paid repositories features or support. Sure you can just compile it yourself but that’s kinda the same thing Zorin is doing: https://lemmy.world/post/29546682/17016426
