Not OP, but my understanding is that the browsers 'compete' much less than the public thinks they do. The developers attend conferences together, they co-fund initiatives like the MDN, they ultimately collaborate on a common spec. Google wins as long as people are encouraged to spend more of their time online. Firefox needs market share to sell homepage defaults. Apple wins as long as desktop and mobile capabilities converge so that they can sell iPhones but remains hard to monetize so they can sell apps. No one wins if antitrust regulation gets involved.
