When the news about the follow dropped, I was 99% sure it was a hack.

But he's still following. Together with the other Meta people following too, a random coincidence feels less likely to me. Still no proof of anything, but it keeps the thesis interesting.

One of these anti-hype plays I've been liking lately.

Wait for the first storm to pass, then see if the thesis still holds while many of the people who bought purely for the hype have already jumped ship.
