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
I’d guess it’s either an issue of incorrect metadata in the Flatpak, or Flathub doesn’t recognise the MPL2 license.
