Apple always had an arrogant marketing. It’s part of their DNA. Especially when they merely catch up with their competitors they claim to be the first, the fastest and the best.
This make sometimes difficult to understand when they truly innovate.

Anyways as long as Webkit is gaining users, it will also benefit to Firefox and Opera (and vice-versa).
