Switching from one email service to another instead of self-hosting, isn't he just trading a cow for a cattle?

IMHO, the key is using your own domain. It's fine to outsource the actual running of a mail server to professionals if you can freely choose who that is, and switch if your opinion changes, self-hosting being one option.

There's a privacy tradeoff in using your own domain for email.

That's true, and I personally keep some "unbranded" e-mail accounts for those cases, even if I can't move those.

You also add a potential weak point in that not only your e-mail account, but also your registrar/DNS accounts could be compromised.
