> Facebook could now freely use your patented idea, and violating it left, right, and center, and if you try to sue them for violating that patent, you're completely fcked.

Maybe, maybe not. You suing them over your patent would terminate you patent* license from Facebook, but not your copyright license. Whether that fucks you or not depends on whether or not you actually NEED a patent license from Facebook.

As far as I know, no one has actually found a Facebook patent that covers React.

Interesting. If that patent issues, is it going to be a problem for any React alternatives, or is what is described there unique to React?

Also, I'm curious. When did React start using the techniques covered in that patent application?

This would make Reacts PATENTS file a bluff (nothing to grant or revoke). I don't think many companies would be eager to base decisions on that legal theory.
