Facebook React.js License
I think the change in licence has something to do with mobile phone licence issues, React Native had its first official release on a date that correlates to the licence addendum changes, this is the first official tagged release :<p><a href="https://github.com/facebook/react-native/releases/tag/v0.14.2" rel="nofollow">https://github.com/facebook/react-native/releases/tag/v0.14....</a><p>As you can see it is dated: "10 Nov 2015" shortly after the licence was changed.
