The problem was that:

1. They chose to insert the clause and refused to use standard MIT license despite complaints from community and their own developers

2. They are the kind of company who chose to do shady stuff despite complaints from community and their own developers

#1 was fixed. #2 is still the case and may come to bite back in future. That is the concern

Well, I'm pretty happy using it and I certainly don't lose any sleep over Facebook having built it. Quite the opposite - I thank them for it! Nobody can take away my rights to freely available MIT licensed code.
