As you have seen in my last post or elsewhere, Facebook has recently added a dubious patent clause in the license of multiple projects including ReactJS. And predictably, a number of organizations, companies, and open-source advocates made it clear that it’s way too dangerous to keep on using the code with such restrictions because of possible legal repercussions.
Well, I am pleased to tell to all my readers, that they have back-tracked on this after Apache Foundation, WordPress, and many others have express their clear intention of switching to safe alternatives to React.js and other frameworks from FB, or banning their use. As you all know, FOSS is a free market ecosystem; it is thriving from the forces of intellectual competition, always offering multiple choices to its users. And this approach won again: facing the danger of loosing their user base and, effectively, rendering themselves irrelevant, they made the decision to, once again, re-license some of their projects under MIT.
Namely, ReactJS will be released under the new license. So if you are using it – make sure to update your dependencies to v.16 once it is out next week. Remember, re-licensing isn’t usually retroactive, so don’t fall into that trap.

And let the Dao be with you, as usual 😉

What is to stop them in a year or so when it is to late for some. I think they just pulled the trigger to soon. They will do it again! F-FB! Thanks for the heads up!
