"You can't correct Coda. He doesn't care."
I know that. What I might be able to do, though, is explain why his example might be a bad one to follow. Or maybe it's a good one, for those of the "no publicity is bad publicity" mindset. In any case, I think it's worth it to express my view. These things do affect businesses and livelihoods. Maybe it's too "meta" for some people, but - unlike some - I won't tell people who disagree that they should remain silent.
"I think this is a bad direction for our threads to go"
It's not only a bad direction for "our" threads to go; it's a bad direction for the broader discussion - across here, Twitter, various blogs, etc. - to go. That's my point. HN isn't an island. I've seen quite a few people who disable comments on their blog posts and explicitly direct readers to the corresponding post here for discussion. The real damage to real reputations is being done elsewhere, and condemning those who point it out here seems counterproductive.
"I don't think you can talk about "de-escalation""
Ad hominem, pure and simple. I'm not one of the principals here. I have nothing to do with the companies or communities involved. As a mere commentator, nothing I say affects those relationships one way or another, so de/escalation is an inoperative concept. If you want to disagree with me fine, but please stop finding new ways to tell me I shouldn't even have an opinion.
