I am very new to linux and all the open source stuff (my first post on lemmy actually) so I don't get how this stuff works but flathub is saying that floorp is proprietary. But after a quick google search it says that floorp is open source licensed under MPL 2.0
Sounds like bsd with extra steps
It's way worse.
With bsd you could at least take the code you got and make your own fork, with these shared source licenses you get nothing.
