Chris Coyer on CSS-Tricks:

The Safari and Chrome team both want to make the web safer and work hard to improve the web. But they do have different views on what the web should be.

And:

I’ll say how I feel: that sucks. I have this expensive computer in my pocket and it feels unfair that it is hamstrung in this very specific way of not allowing other browser engines. I also have an Apple laptop and it’s not hamstrung in that way, and I really hope it never is.

I do think it's a little annoying when people say "if you can't do it on the App Store, do it on the web, the web is totally open," since Apple really does have a ton of control over the web on iPhones and iPads as well. Maybe not so much on the content of the web, but the ability deveopers have to create app-like experiences with web technology.
