I do agree with you - it is appalling how much power Google has. I think a bit of perspective is helpful, though.
There hasn't really been much of a span where there wasn't a de facto 900 Lb gorilla browser that threw its weight around. I think a lot of us watched this happen, but the various charts on this page are instructive:

It appears that somehow the browser market trends toward an unstable near-monopoly of sorts, at least so far.
So, meet the new boss, same as the old boss. At least https everywhere is a long-term public good that they're willing to take grief over forcing. It beats some of the other unilateral changes various once-dominant browsers forced.
