How do expect anyone NOT to be upset at MS for making changes to things that are loved by the WP community? Take the OneDrive syncing from photos or FB integration. We love those features. They work, and they work really well. And for MS to remove it at the request of NOBODY makes people mad. It is completely unnecessary. It's understandable for users to be fuming at these types of changes.
I have to imagine there's more to this story than meets the eye. I don't think Microsoft would have pulled this feature just because they felt like it. I wonder if there was some push back from Facebook on that integration and they were forced down that path.
