They aren't your typical average Twitter users, they're artists (although not the industry-professional kind; one is making small indie games, and the other is drawing fanart). Those small-scale artists (who are earning barely enough money for their skills) are probably gonna look down pretty harshly at the investors who seem to look at dollar signs as the ultimate goal... I guess the language is a bit harsh but I could understand.

(Maybe HN isn't that sympathetic to those type of people, so I might get downvoted to oblivion - but you still can't generalize them as average Twitter users...)
