But what about if you're a large company with a large patent portfolio, you don't intend to abuse silly software patents, but it would be irresponsible to de facto grant Facebook free license to all your patents?
If I'm doing a startup, this clause is no issue. If I actually have patent assets, this seems like a non-starter still.
I was among the people who warned about the unfairness of the previous license. I am a Free Software advocate, so I have no problem with allowing Facebook to use any patents I might later obtain, as long as using React (and similarly-licensed software) does not leave me defenseless against a FB lawsuit.
