Anyway, while I don't understand why this pisses some people off so much, or why they take my critique of the Mastodon PM semantics so personally, it's now very clear that it does piss some people off quite a bit.
But I'm not going to let that stop me. I'm an expert on security and privacy. And my job is, in large part, to act as a public intellectual. Warning people of dangerous designs that could cause them harm is what I do. If doing so makes me an asshole, so be it.
