I have an idea of where the app developers are.
they are in an ecosystem that put up with a language that calling niche 10 years ago was flattering.
or they are in an ecosystem that is so fragmented that you can forget complaining about three or four major distros, when you have to deal with five different major versions on dozens of devices and form factors, all with minimal or no upgrade paths.
more importantly, though, I think that the app developers are where stuff looks cool and where the community leaders don’t eat their children in constant whining on public venues.
