Whoa. Dang, I have to say, I feel a little slighted. I'm neither ignorant, nor wrong, and I'm aghast that you would insinuate that.
I've contributed faithfully to this site for a decade. The other commenter has -15 karma because, as you noticed, his comments are largely childish, combative and unsubstantive. It's embarrassing that you are validating him.
His claim was that Google publishing DKIM keys as described in the article would be "destruction of evidence", but that's provably untrue since there would be neither intent or willfull neglect on anyones part.
Literally (yes, I mean literally) no-one else here on HN, or anywhere on the internet, has legitimately attempted to argue this. It just doesn't hold up to basic scrutiny. "Destruction of evidence" is a very specific legal term with very specific meaning [0][1][2]. He seems to be distorting it in a Guilianni-esque fashion - "It's fraud! ....But no, your honor, not in the legal sense. More like in my own made-up imaginary sense!".
I've been restrained and as courteous as possible (under the circumstances), but even after you tried to squash the thread, and I stopped commenting, he's continued to insult me. You seem to be tolerating it.
I would have appreciated it if you enforced sanctions against obviously bad actors and remained completely neutral. That is what you're known for, but I respectful think you've failed in this case. At any rate, I know you have just about the hardest job on the internet, so I'll go ahead and chalk this up to misunderstanding.
