Is the “fediverse” some sort of secret club that I’m unaware of or something?
The whole idea of the “fediverse” is that some aspect of it is cross-company, and federated across instances. Email fits that term exactly. The wiki entry doesn’t exclude email via the comparison, if anything it makes more of an argument that email is one of the first federated services to exist. The “fediverse” is just the collection of those federated services.
