If one person believes one thing and another person believes the opposite, that doesn't mean they're hypocrites. That means there isn't a consensus. Besides, android can be better than iOS and deserving of criticism at the same time.
Or maybe people hate Google ruining the internet AND realise that iOS is still much worse than Android? The two things are in no way mutually exclusive unless you view the world as a tribal binary.
Chromium is open source, too, but so many projects putting all their eggs in the same basket gives Google carte blanche to push any standard they want as a new de-facto standard before the rest of us can decide on whether it's ready or needs changes or is just bad.
