Facebook says Apple is too powerful – they're right
Apple is way too powerful. Not that Facebook is any better, but Facebook is not the gatekeeper for millions of peoples lives. When Apple boots you as a customer, you most likely will lose everything about your digital life.<p>If you lose your Facebook account, it's annoying but recoverable.<p>Apple has control over your phone, your passwords, your photos, your music, your emails, your credit cards/payment methods. And you can backup nothing of it in a usable way. 
Without a working Apple account any iPhone is as good as a brick.
