Here is another large project (Drupal) that decided against React because of the PATENTS file: http://buytaert.net/selecting-a-client-side-framework-for-dr...

"The Virtual DOM, among React's most compelling features, has also seen its core ideas filter into other framework projects. But more importantly, React is licensed with what I believe to be a potentially unacceptable patent clause, which states that an organization can no longer use React once it sues Facebook for any (unrelated) patent infringement. This has already generated some concerted pushback from both WordPress's Calypso and React contributors."
