That’s cool. How did you go about finding that? Any communities you can recommend?

This may be a stupid question, but how does an app being on Play Store and not F-Droid make it no longer FOSS?

I feel like Windows 7 fills the sweet spot between the seemless UI of the 2000/XP era and newer versions. Windows 10/11 could top that list if Microsoft had bothered to create a proper UI instead of just slapping some material design on a handful of apps, while everything else is still basically 2000/XP. Then again, GTK2/3/4 can be almost as bad.
