Someone did ask EY whether the fact that he signed up with CI whereas Hanson signed up with Alcor meant he disagreed with him about something important about the two institutes, and IIRC he answered it was just that Hanson was richer and older than him so of course he'd chosen the higher-end option. (I cannot find that comment, since even a search for Eliezer CI Hanson Alcor in the internal LW search engine turns up umpteen pages.)
