He totally dismisses Groupon's rejection of Google's offer, when there were almost certainly some sort of earn-out. I'm sure if Google were offering $8B in cash with no performance requirements, they would have taken the money. But that's not how deals work, and Groupon could very well have decided an IPO would lead to a much surer return.

I would expect a less shallow analysis from a finance guy.
