This is all amusing. Not that it matters, but when I said "expert" I really meant any user that understands how to use PGP. Those of us born during the construction of the pyramids know how to use it because it was the only option that existed back then, and we still have that knowledge despite other options existing. Signal and other options are great, but you can't encrypt arbitrary data with it. PGP is really a different use case these days. And the ancients that still write emails.
