> they know the risks of being dependent on Google
I wouldn't argue it's that risky. Look at their past entanglements:
1. Google Default Search Bribe - brings in $20B a year for literally doing nothing
2. Google Maps: Google let them build their own custom app using Google's backend, and it worked fine all the way up until Apple chose to exit that arrangement
actually I can't think of any others, but is there an example of Apple getting burned by Google?
Well they have an illegal monopoly over display ads that they defended with a moat of money when FB tried to butt in, so that's an example of them being not great to rely on.
