Simple version: If he thinks and thought the Groupon scenario is "absolutely disgusting" why did he advise, take a board position, and retain shares in an "absolutely disgusting" venture?
You're just a little obsessed with parsing his every word. Maybe he did find Groupon's growth absolutely disgusting. Maybe he didn't. Either way, he was asked to participate and give advice, which is what he did. One can do that and not be thrilled with everything going on. We're not talking about criminal activity here, just one of many ways to run a business.
A bit confused why downmodded for responding to a request for clarification with a clarification. If you don't like the original post, isn't downmodding that enough for you?
Options presented by me:
A) "absolutely disgusting" is an exaggeration
B) JF is a hypocrite
C) JF has changed his mind over time
