There might be, but I doubt it's on purpose. At best it'd be gross negligence or something, but I'm not sure holding a monopoly by not actively supporting the opposition (i.e. negligence) is punishable.

I experience the same issue and it's frustrating. Not that I use a lot of Google services, but when I do... yeah the effect is noticeable. So much as I like to point a finger, I expect it's just due to them not putting in as much time to make their stuff run perfect in anything other than Chrome.
