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
From the Floorp official website:
Floorp’s source code is entirely open, allowing anyone to view it and contribute to the project. Not only is the browser itself open source, but the build environment is as well.
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.
