>filters 90% of the bullshit.
Why would Apple want to filter out people from integrating with sign in with Apple? I can see they want to filter out junk from the App Store, because junk on the App Store (like junk on Something Awful) reduces the signal to noise ratio. But I don't think there exists a signal to noise ratio when it comes to sign in with Apple. A user wants to join a website, and that website either supports sign in with Apple or it doesn't; there's no noise to wade through.
