Why would someone who doesn't give a shit say something like
"I’d rather suck a dog’s nose dry than lend a hand to the nerd slapfights on Hacker News."[1]
That sounds like the attitude of someone who very much does give a shit about HN enough to not like it.
And besides that, while I may agree with what you're saying in principle, in practice it's bad business to go around insulting such a large number of potential clients/employees/partners. It's better to keep your mouth shut if you don't have anything nice to say.
