This development should inform the decision on what JavaScript framework to adopt in WordPress core. While Automattic and its lawyers may feel comfortable using React under its current license for its corporate endeavors, WordPress is an open source project through and through, and I am not sure the current React license, and in particular the reasoning Facebook uses to apply that license, is in the spirit of open source as WordPress defines it.

I hope the discussion of what JavaScript framework to adopt in core will include an extensive legal analysis.
