> Yes, because it ignores the sentence that precedes it.
This sentence? "Serious secure messengers have been designed to avoid non-repudiation since OTR." I don't see how this sentence supposedly alters the meaning of the sentence that comes after it? At this point it seems like you just want to sow confusion. If I had misinterpreted your words in some way, you could have clarified the misunderstanding like 10 times by now. Instead, you choose to reply in snarks like saying I'm confused, or asking me to read your comment again. I don't think there's any misunderstanding. You took an extreme position that didn't hold up to scrutiny, and you don't want to defend your position or back down, so you just reply in snarks instead. If there is some kind of misunderstanding, please do go ahead and explain what the misunderstanding is.
> "once counterparties have authenticated each other's messages" is the omission that changes the meaning of the quote.
No, it doesn't. The dispute isn't about the need for counterparties to authenticate each other. Yes, we all agree that it's good if email receivers can validate the authenticity of the sender. That's not at dispute. The question is, is it good if third parties also have the ability to authenticate the sender of an email at a later point in time (using DKIM specifically). tptacek claimed that there is no legitimate need for such a thing, and I provided a counter-example to that.
