He's making a video as a post mortem to this experiment, so it might still be released. But I can see why it would be better not to share them (aside from privacy/legal concerns as there was no such release agreement), some of the contributors used their real names, I may be one of them. It could be a bit shameful to see this attached to your real name. They might have submitted their initial draft and then, due to circumstances, could not update the results in the several hour window that was afforded to you.

Luckily my pixels look correct though.
