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
But it is not FOSS. As another person said, it is source-available which is still a kind of proprietary software.
It changed recently

As I replied to the other comment, I wasn’t aware of the recent happenings. I’ve been using Floorp for a while now and when I installed it it was fully opensource.
However, it seems like it’s fully opensource again now (sources in the other reply)
Tbh I still wouldn’t trust them because they made some stuff proprietary for a while. It seems a bit sketchy.
