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
It's just your average cultural clash.
Most people on internet are accustomed with English naming culture. Meanwhile when people from non-Western (mostly US) making name that seems cool in their culture, it often lead to cultural clash. This also applies to symbol, gesture, etc.
The same kinda people who name their browsers Firefox or Chromium. We just got used to those names.
Firefox = fire + fox, not too crazy of a name
Chromium = literally just an element, how is that a weird name?
Meanwhile floorp sounds like a noise an alien would make
