Great read. Facebook doesn't deserve all this flack directed at them, and I wish more people offered this kind of technical breakdown
I looked at react during the first hype was alerted to its license terms right here on hn by other people who understand the difference between software with a termination clause for those who sue to gain exclusive/royalty rights to the particular software and software with a termination clause for those who sue a particular party engaged in a significant amount of unrelated activity.
All that has changed recently is that more people are questioning their strange assumption that it doesn't matter since it is incongruent with fb again putting a recent rework and then substantial defense into something that "doesn't matter".
