lots of users + all-at-once release = lots of crying.
but that also means everyone has the same setup, same problems, and stuff gets fixed quickly.
that's my experience anyway. it'd be fun if someone tried a side-by-side daily-experience report of say ubuntu, windows, and macOS. our own personal perspectives are always colored by time and chance.
Then why is there so much crying all over HN over how hilariously broken any new macOS release is?
