I should have clarified that I meant a lot of the criticism sounds like sour grapes, not all. The point I want to make is that if it wasn't public knowledge how much money these guys took, I think the reaction on HN to these ideas would be very different. My guess is that the 40M scandal makes it pretty much impossible for these guys to get a fair shake in the developer community.
Nitpick: you might call that envy or schadenfreude, but it's not sour grapes. Sour grapes would be if someone were talking down the desirability of $40 million itself.
