Apple knows that for most people (unlike this website's audience), the privacy concern is not as important as using That Cool New App, and if this was just another option developers could, but didn't have to implement, many apps would choose not to -- and most people would still download them. The only way to make sure that most users' email/login/usage isn't being sold or used to track them is to force developers to offer Apple's auth option, and make it as easy to use as choosing to log in with Facebook or Google. > I can't even imagine what would happen if Google did the same thing with Google Sign In and the Play store. If Apple made its money by mining its users' data, there would be a big uproar about this announcement, too. But Apple made it very clear that they will not be doing that with this data, and is moving more and more towards establishing itself as the privacy-focused alternative to Google... So this is by and large (and obviously there are many people with reservations, whether about Apple forcing developers' hands, or about trusting a big company in general) being seen as more of a Good Thing.
