Big companies like to bury unpleasant news on Fridays: A few weeks ago, Facebook announced they have decided to dig in on their patent clause addition to the React license, even after Apache had said it’s no longer allowed for Apache.org projects. In their words, removing the patent clause would "increase the amount of time and money we have to spend fighting meritless lawsuits."



I'm not judging Facebook or saying they're wrong, it's not my place. They have decided it's right for them — it's their work and they can decide to license it however they wish. I appreciate that they've made their intentions going forward clear.



A few years ago, Automattic used React as the basis for the ground-up rewrite of WordPress.com we called Calypso, I believe it's one of the larger React-based open source projects. As our general counsel wrote, we made the decision that we'd never run into the patent issue. That is still true today as it was then, and overall, we’ve been really happy with React. More recently, the WordPress community started to use React for Gutenberg, the largest core project we've taken on in many years. People's experience with React and the size of the React community — including Calypso — was a factor in trying out React for Gutenberg, and that made React the new de facto standard for WordPress and the tens of thousands of plugins written for WordPress.



We had a many-thousand word announcement talking about how great React is and how we're officially adopting it for WordPress, and encouraging plugins to do the same. I’ve been sitting on that post, hoping that the patent issue would be resolved in a way we were comfortable passing down to our users.



That post won't be published, and instead I'm here to say that the Gutenberg team is going to take a step back and rewrite Gutenberg using a different library. It will likely delay Gutenberg at least a few weeks, and may push the release into next year.

Automattic will also use whatever we choose for Gutenberg to rewrite Calypso — that will take a lot longer, and Automattic still has no issue with the patents clause, but the long-term consistency with core is worth more than a short-term hit to Automattic’s business from a rewrite. Core WordPress updates go out to over a quarter of all websites, having them all inherit the patents clause isn’t something I’m comfortable with.



I think Facebook’s clause is actually clearer than many other approaches companies could take, and Facebook has been one of the better open source contributors out there. But we have a lot of problems to tackle, and convincing the world that Facebook’s patent clause is fine isn’t ours to take on. It’s their fight.



The decision on which library to use going forward will be another post; it’ll be primarily a technical decision. We’ll look for something with most of the benefits of React, but without the baggage of a patents clause that’s confusing and threatening to many people. Thank you to everyone who took time to share their thoughts and give feedback on these issues thus far — we're always listening.

Update: This post received an incredible response from the wider web and open source community, and a few days later Facebook reversed their position.
