It ruins every single discussion on the topic when armchair lawyers wade in. I have no doubt that we'll see commenters now provide their own opinions on this clause without having the faintest idea of what they're talking about.

If nothing else, the list of very large companies making use of React, seemingly without concern, makes me unworried about this.

I agree that having this issue dominate discussion is incredibly annoying, however I have to say, Facebook needs to make this more clear. There should not be confusion about this.

This, I do agree with. Like I say, I'm not bothered about this issue, but I'm sick to death of seeing the endless stream of internet warriors throwing themselves at it. A clarification blog post would help a lot.

The fact that large companies are making free use of this surprised me. Is it because they don't think that the seconds clause is actually enforceable? I would love to hear more on this.

I saw this [1] from one of the (ex-FB) React devs after the last bout of this on HN:

> it's "be a patent troll and suffer the consequences"

What exactly is the controversy? Seems fair enough to me.
