What specifically about the licensing? This is an actual question, not advocacy. IIRC, Facebook had a provision that disallowed use of React for a ridiculously broad range of offenses with respect to any of FBs intellectual property but that they narrowed it considerably last year to a more reasonable: you aren't allowed to use any of our intellectual property in React if you dispute our ownership of that specific property. I could be characterizing this incorrectly, or you could be referring to something I'm not aware of, so what specifically are you objecting to?
