I, for one, wouldn't ever use a service that requires login via social media or some other platform, especially FB/Google. This isn’t usually a problem, though - I don’t think I’ve ever encountered an app that would impose this. (Maybe apart from services that are specifically built on top of the app that they’re authenticating through.)
