I didn't know this, this needs to be more well known.
How does this affect libraries like preact?

Acting like this is some landmine that allows Facebook to just put anyone they dislike out of business is ridiculous. Other JavaScript frameworks like Angular and Ember don't even include patent clauses, so even if Facebook revokes the patent grant, that leaves you in the same position that you're in by default with Angular. The license even specifically allows you to counter-sue Facebook if they already have a lawsuit against you.
Any confusion that arises from deciding to depart from well-understood licenses is fairly laid at their door, in my view.
That's true; however,
> React isn't known to be patent-encumbered.
That's a useless assertion. Many patents only become known once the lawsuits start. Facebook has amassed a patent portfolio, and patents are a legal instrument that can only be used offensively.
Remember, the claim I was disputing was that "only a fool will use reactjs" because the patent license is conditional. All I'm saying is that I don't see any reason to be more concerned about React than, say, Angular.
