I'd certainly rather use Apple (“we don’t sell your personal data or use it in our thousand other products or leak it to everyone on the planet”) than Amazon or Android (“privacy is for our CEO, not you”).
As for the worst Google can do, we already know that. They can and will give and sell it to all sorts of sleazy people. Amazon is worse.
Your phone company is probably worst.
