It's not "termination on any action against Facebook", the termination is only for:
1. filing a patent infringement against Facebook (for anything, related or unrelated to React)
2. filing a patent infringement counterclaim against Facebook for patents related to React (after Facebook have first filed a patent infringement claim against you for patents on anything)
3. filing a patent infringement against anyone for patents related to React
[edit]
> if Facebook infringes on patents you own you can't take action against them if you are using React.
You can take action against them, you just don't have a patent grant once you do.

Which opens you up to being countered-sued right? It seems that this leaves Facebook to freely infringe on any patents of React users without consequence.
Not without consequence. You as a company will have to determine which is more of a problem: Facebook using your patents, or you using Facebook's patents.
