In reply to Albert E..

This is an interesting point... but it triggers the question "who would have to sue Facebook for patent infringement to trigger removing React from WordPress? Me? You? .org?

It all untested law... but, no, I think one would assume it just means that I wouldn't be able to continue using WordPress (with React baked in) if I chose to sue FaceBook for patent infringement.

Yeah, I don't like software patents, but I like my legal rights being given away even less.

As I've said elsewhere. It's _not me_ it's my clients.

I would no longer be able to use WordPress for clients sites without also advising them that should they someday want to sue FB for patent infringement they'll loose use of WordPress. For some of them, as edge case as that sounds, that will be a deal breaker.
