It continues to baffle me that Matt, one of the foremost champions of GPL, doesn't have a problem with this. It's absolutely not a "free" license if it restricts your freedom to sue Facebook.

While I'd love to see multiple downstream consumers band together and get FB to move back to ALv2 on this, doing so is "wouldn’t be too optimistic about this" in their own words.

Switch to Vue.js before it's too late. Gutenberg is a nice POC, but there are lingering UX issues, rebooting wouldn't be the end of the word, yet...
