He socialized with Epstein (post conviction? looks like he did![0]), ran in the same circles (publishing in that that ridiculous "Edge foundation" thing[1]) and threw him under the bus only after he was safely declared dead, apparently seeing nothing wrong with Epstein's grotesque antics as long as the spice was flowing[2].
It's not the worst thing I can say about him, and in fact isn't the worst thing I said about him above, but, well SOMEBODY is a little sensitive. I think "social climber" is a pretty accurate, even generous description for this sort of behavior.
