> There’s already a license for BSD+PATENT, and it’s called Apache license. Is Apache setting a bad precedent as well?

That comparison is incorrect because the termination clauses are different. The patent license under Apache only terminates if you sue about the specific patents covering the software. By contrast, the Facebook patent license terminates if you sure Facebook (or an affiliate -- who is that?) over any patent whatsoever (including patents not covering the software, such as unrelated patents you own and which Facebook is infringing willfully because they know you dependent on React in your products).
