@harrisbueller Perhaps I am explaining it incorrectly because you are correct. My thoughts really revolve around the idea that ISPs provide users with Mastodon instances as part of the bundle they pay for which their users may or may not sign up to. But even that is not quite there. It is more around major players making these service instances available to take the load off a small set of volunteers and making it as ubiquitous as email. Signup could be as untied to the users' ISP as Gmail is.
