As an app developer, I think that I've done "Facebook SDK integration" task over 10 times at the very least. I don't think I'm the only one. It's unrealistic to expect a mobile app not to offer a user the option to login through Facebook. And yet, we don't need to integrate Facebook's binary blobs to use this SDK's main features. How about we implement the open version of Facebook SDK that uses their APIs but doesn't do anything that we don't want it to?
