Yeah, I've been trying since November 2015 to get Automattic to understand the Facebook BSD+PATENTS problem with their Calypso frontend to WordPress that uses React. Just added another comment to the issue linking back to this story:
"Replace React with Mithril for licensing reasons"
https://github.com/Automattic/wp-calypso/issues/650#issuecom...
Of course, that issue was rapidly closed with essentially a "we don't think there is anything to worry about here" -- ignoring that even if Automattic may not have patents to defend, any of their customers who has patents could face an issue using Calypso.
All this is made more confusing by the fact that Facebook changed the React license over time from Apache to BSD+WORSE_PATENTS and then to BSD+LESS_BAD_PATENTS. And it looks like Automattic may have started using React when it was Apache licensed. So they got the rug pulled out from under them by trusting Facebook. I can wonder if their code might be considered to have grandfathered Apache patent licensing rights?
The Fuchsia license by Google (at least the one file I looked at) does not seem to me to be that different from other FOSS Patent licenses in that it is not as broad as Facebook's and just covers patent claims about Fuchsia itself. So I would not put it in the same category as React's much broader PATENT retaliation clause which applies for any disagreement over any patents with Facebook whether they are related to React or not. So it is more like if you sue about Fuchsia patents you can't use Fuchsia.
