I've had a bad experience with him and in general I think he's toxic (his beliefs are more of a religion rather than scientific). He is unwilling to accept any evidence that contradicts his opinions. I don't think offering help hurts, but we should be aware that it can backfire.
E.g. he is the kind of person that if we publish some message about a new foundation model or another message he doesn't approve of, he'll use the fact that we helped him against us in a loud, destructive manner.
