When you say you got his point, did you mean you get how his point is related to charging people to pitch? I am completely willing to grant that such people exist and are unpleasant, but what relevance does that have here?

No, the point about how some entrepreneurs have a sense of entitlement. I think people reacted poorly to that here because they interpreted it as 'how dare you ask angels for investment', which would be offensive considering how many people struggle just to become ramen profitable, often for a long time before cashing in, if ever. Then there are other people who want to be compensated on the basis of projections rather than receipts. It's a blurry line since we know some companies where the founders make $$$ long before reaching positive cash flow.

As far as the 'pay to pitch angels' go, maybe they'd be better off describing themselves as a capital sourcing service or enterprise microcredit bureau or something, since people take 'angel' to mean someone willing to help when you've got nothing. I empathise with the tedium of dealing with self-promoters who think they're god's gift to business despite having money; on the other hand surely the payoff of being an angel is having founding capital in the one project out of 50 or 100 that hits the jackpot and eventually goes public.
