If Amazon were as ubiquitous as Facebook, we would.
In most situations where we've used a Facebook login, it's simply to avoid forcing the users to create yet another account. We don't pull any real data (except maybe a couple things, again, for their convenience - to fill out their profile) like their name. We push nothing back.
Being able to say "Hey, just login. We don't actually care about your information." would be much preferable to Facebook's unnecessary "This app is requesting permissions to access your profile and friends list." We don't need that information.
I guess maybe that's our fault for abusing Facebook integration by using it simply as a single sign-on service.
