You will by definition be standards compliant if you are the main mover behind the eternally moving standard. Chrome powers the living standard. Other browser engines follow.
They cooperate for now, but the balance of power and momentum is heavily in favour of Google as it stands. This will only matter when one of the others wants to hold out on some critical feature and find that they effectively can't if they don't want to see their already minor market share plummet. Apple though do have some clout since they own the entire vertical...
So we have gone from Google powering the living standard to the prediction that they will be able to dominate it at some hypothetical point in the future.
Well, maybe. Who's to say? But if we're theorising, I'd say that Google probably learnt a lot from IE's demise and most likely sees the advantage of making sure that the web dev community at least does not actively hate them.
I thought we were talking about other browsers "wanting to hold out on some critical feature and finding that they effectively can't if they don't want to see their already minor market share plummet"?
Which is kind of a weird thing to be arguing for anyway. If a company wants to innovate isn't that a good thing?
