今日，Facebook在其網站上發佈。
下週，我們將重新許可我們的開源項目，React、Jest、Flow和Immutable.js，新的協議將使用MIT協議。
雖然我們仍然相信BSD+專利許可提供我們項目的用戶一些好處，但是我們承認，我們沒有說服這個群體。
Next week, we are going to relicense our open source projects React, Jest, Flow, and Immutable.js under the MIT license. We're relicensing these projects because React is the foundation of a broad ecosystem of open source software for the web, and we don't want to hold back forward progress for nontechnical reasons.
This decision comes after several weeks of disappointment and uncertainty for our community. Although we still believe our BSD + Patents license provides some benefits to users of our projects, we acknowledge that we failed to decisively convince this community.
In the wake of uncertainty about our license, we know that many teams went through the process of selecting an alternative library to React. We're sorry for the churn. We don't expect to win these teams back by making this change, but we do want to leave the door open. Friendly cooperation and competition in this space pushes us all forward, and we want to participate fully.
This shift naturally raises questions about the rest of Facebook's open source projects. Many of our popular projects will keep the BSD + Patents license for now. We're evaluating those projects' licenses too, but each project is different and alternative licensing options will depend on a variety of factors.
We'll include the license updates with React 16's release next week. We've been working on React 16 for over a year, and we've completely rewritten its internals in order to unlock powerful features that will benefit everyone building user interfaces at scale. We'll share more soon about how we rewrote React, and we hope that our work will inspire developers everywhere, whether they use React or not. We're looking forward to putting this license discussion behind us and getting back to what we care about most: shipping great products.
MIT協議又是什麼呢？
對比之前的協議內容
如果你採取專利主張訴訟或者其他方式挑戰 Facebook包括其子公司及其合作），那麼你使用 React 的許可會被立即撤銷。
你也不能與其他使用 React 的公司發生專利糾紛，否則你使用 React 的許可也會被撤銷。
當然，大家還是會很歡迎Facebook這樣的改動。
偷笑：上次停用React的時候，真的以為Vue的春天倒了
