Google has already given Chrome an unfair advantage by leveraging their other services. I suspect the browser market is an unstable system where absent outside intervention Chrome’s 65% market share naturally becomes 100%.

Chrome is such a complicated piece of software that the “forks” are highly dependent on Google and when Google unilaterally makes decisions they have to follow suit.

I think a lot of people don’t appreciate how delicate the balance of web standards is right now. We have it so good (three high-quality implementations of an open spec) and I’m not willing to throw that away just to run Chrome on my iPhone.
