The domain does not provide extra privacy, but it does not ditch extra privacy also. buttman@gmail.com vs butt@man.com are two emails addressed to you, but no one knows who you are.

Rather, it provides a framework to be a digital nomad, switching email providers at a whim while not needing to do account recovery. An @protonmail can’t do that.

I essentially read the “what’s the point of privacy if you have nothing to hide” argument. I don’t do drugs or run a torrent tracker.

mistakes do happen and especially with services featuring a free tier, they have so many users they don’t have time to double check their actions or care about providing good support. I already provided two examples of pretty notable people getting banned from Google for unknown reasons and still not being able to get their account back.

Closer to home, let’s look at Lemmy. As it’s still small, the admins interact with the users and think twice before banning. Reddit on the other and is the opposite, because they quite literally have a million times more people to worry about.
