>Apparently in response to criticism, in April 2015 Facebook issued a second version of the Additional Grant of Patent Rights that softened the termination provision to say that the React software licensee would not lose its right to use the software under Facebook patents in the special case in which the licensee brings a patent lawsuit that is a counterclaim against Facebook or its affiliates that is unrelated to React.js. The second version of the Additional Grant of Patent Rights, in addition to the BSD license, is what governs use of React.js today. Sorry, seems it only applies to counterclaims.
