If that's not your intent, you're just making personal attacks on the creator as a complete non-sequitur to the thread, which is even more of an inappropriate abuse of the HN audience than well-poisoning would be.
Yes, exactly. They say themselves: "They could be right, they could be wrong, better engineers than me will tell in the end." They have no interest in the topic at hand, just poisoning the well, then defending their thinly veiled well-poisoning.
I know it doesn't really make a big difference to your narrative, but you really need to pick one or the other of "political non-sequitur" and "interested well-poisoning". They just don't go together.
Otherwise, I'm here to talk if you are.
They could be right, they could be wrong, better engineers than me will tell in the end. So what? Saying something true doesn't create an obligation to listen.
In fact, if you say enough true things loudly enough, they'll cart you off to jail. It's really not a great argument.
