I know it’s probably an unpopular view, but I’ve found it to be true a lot.
It’s not. It’s the same reason why Linux is everywhere that isn’t specifically consumer oriented and front facing. Even most UIs that are designed to mimic Windows are made by tech nerds like us who just assume the users don’t know what they want. But they do, they’re used to what they know. That’s about it. It doesn’t help to say “the Windows UI is garbage anyway”, it just needs to work and feel familiar. I’m sure Linux could actually slowly take off if there was significant effort put into making it as straight forward as Windows on the front end but nobody really cares about that.
