In the 1990s US ISPs would “give you” an e-mail account with their service: you@isp.com. Of course, this is insta-lockin for that e-mail address, you can never port it.
Owning your own domain name and running e-mail service through that worked, for a few years, but the big players have made whitelist / blacklist such a frustrating whack-a-mole game in the e-mail space that running your own e-mail server quickly became impractical.

That’s why all clients are fully open-source. You can also use a fork like Molly.

AFAIK, Signal does not want anyone to use alternative clients, has that changed?
