Thanks for the reference ,but I read your earlier comment

here's the issue when picking reactjs vs others (like vuejs)

Choice A. by picking reactjs I'm in a clear violation of FB patents, but I'm covered as long I don't sue FB.

Choice B. by picking others (like vuejs), I may or may not be violating FB patents, (virtualDOM has some prior art, as some people claim)

why it's so hard for people to understand that "May or Maynot" is a better choice of "definitely" violating FB patents in case I need to sue FB if they are killing my business by copying my patents.

I know that suing for patents is not best business model. But, having that weapon (even defensively) is better than not having one.

still people downvote for gray areas?
