Huh? I'm replying to someone inquiring why someone else didn't review a fork. Aka, the GP was focused on the Fork aspect of Hippy, and the Parent asked about React, as if React was a fork.

I think you misunderstood the comment chain. I was not even talking about security issues or how that affects forking. I was merely replying to another discussion about forking, and how React is viewed in that "forking light".
