Earlier quoted context omitted.
Don't let Apple PR fool you into thinking commercial decisions like this are anything like principle based :-) If Amazon, Uber and Lyft drop iPhone support, people will atop using iPhones and that's pretty much the only reason Apple doesn't charge them a commission.
You think people will stop using iPhones because a ride sharing app goes away? Ever wonder what would happen to Uber and Lyft lost iPhone customers as a user base?
That could definitely put a hamper on new iPhone sales.
