(IANAL, I did complain here about the old patents file)
An older version of their patents file used language that suggested to some that the license would be void if you attempted to defend against a patent suit from Facebook and it could therefore be dangerous to use.
They recently updated the file to clarify some terms, particularly the one the parent is complaining about, and I haven't heard anybody complaining about the new language.
Yep, we had a bit of a brouhaha over the original update to our patents file and clarified the language afterwards, I think it's a bit more straightforward now!
