It's not about 50% globally. It's like 50% of .SE, which is itself less than 25% as large as .INFO. He's guessing, and he's wrong. That's the point of my comment. I don't care what you do with the observation; he brought it up, and he's way off.
(I don't think it's weird that he's way off; I'm not criticizing Mockapetris, just correcting the stat. But your vehemence demands a direct response from me, and I'll provide it.)
I don’t know what you mean by “vehemence”, but I note that even though you said it “demands a direct reponse”, you didn’t actually answer the question.
I'm sorry, I thought I was clear. No, pointing out that Mockapetris' guess of 50% global adoption of DNSSEC is wrong is not an "argumentum ad populum". It is, as I said, simply an observation that the statistic he is venturing is wrong.
