> In effect, you may as well be granting Facebook a patent license to literally all your patents for use in any context, in exchange for using React. I'd say that's overstating the case. You aren't granting them a license to your patents and you can still sue them for infringing (which you would not be able to do if you granted them a license). Rather, you are promising to look the other way for as long as you are using React. Should you choose to sue, 1. You can say in your case that they never had a right to your patents 2. You can take the time to remove your usage of React prior to filing the court case (so that you never infringe).

Point 2. sounds kinda sketchy. Facebook's BSD says that even 'take a direct financial interest in' suing is forbidden. So if you begin cutting React out of your operations and then sue them already React-free they will probably try to claim that for a time you were using their patents in React illegally because you considered suing them before removing it and at that moment the patent grant terminated. https://github.com/facebook/react/blob/master/PATENTS https://github.com/facebook/react/blob/master/PATENTS
