This is assuming that Apple cares very much about browser market share. They're not really a web company, they just need a decent browser to include with their OS. Nothing stops them from switching to Blink (or Gecko) and letting someone else spend the money building a competitive browser that they can just include for free.

Apple cared enough to start the WebKit project. Though admittedly, ALL the browsers for Mac OS X in those days sucked.

And that's the point. They care to the point that their operating systems continue to have competitive browsers available... but now they do. Why keep throwing money at it once you have what you need when others are willing to pay in your stead?
