Gpg isn’t as good as a private messager.
Wake me up when it uses the Signal protocol or something simular.
I like this post and the style of writing, but there’s no way on earth this is “easy” to the average, non-technically-minded person. Never mind trying to convince the average Boomer or Gen X-er to follow these steps, it might exhaust a lot of privacy advocates or other people in technical fields. Heck, I’ve seen technically proficient people complain about the complexities of getting Matrix/Element encryption to work, and by comparison, that’s practically a walk in the park.
(I was originally going to make a slightly more conciliatory comment, but then I realized you were not the OP of the original content. I appreciate the transfer of knowledge to the clearer web.)
