True, but in some ways this is Apple doing a favor for competing browsers. Imagine how loudly people would complain if Apple did the opposite — provided no support to other browsers, and left them to compete without Apple's inside knowledge of its OS and hardware. No other browser could come close, and we'd all be on Safari all the time. While it's not ideal to be forced to use Apple's rendering engine, at least we can access the many other features that alternative browsers offer.
