That's a level of moralizing that isn't really appropriate for analyzing decisions like this. It's equally true, and for essentially the same reasons, that Android as a whole exists because the Google leadership basically assumed Apple would screw them over sooner or later if they could.

Businesses compete, basically. It's a good thing and the efficiencies that result make us all wealthier. It's only "screwing someone over" in the myopic eyes of the internet fan boi.
