I'm not avoiding your question - I'm pointing to why Chrome is in the lead.

If Chrome didn't have Google backing it and Apple didn't mandate Safari, Firefox would likely have significant market share.

This isn't a battle over functionality, it's monopolistic invasion of an open ecosystem by giants that control all of the ingress points. They're turning the entirety of the web itself into an ad/product funnel for giants.

I don't care if Mozilla wins. I just don't think the world is healthy with two OS/mobile/search vendors controlling every major piece of technology.

The technology sector will be healthier if these companies are forced to break up. There will be more competition and more innovation as less is spent fighting for the last 1% of growth.
