Indeed. I'd like to. Except Google also make it nigh impossible for anyone hosting their own email (the original-internet ideal) to get email into gmail reliably enough to be useful. I have my own address on my own domain, but can't rely on it (yes, DKIM and DMARC and SPF are properly set up) not to be marked "spam" for opaque reasons, so gmail remains my "main" address. It's a network-effect problem: once enough people are "captured", then everyone else is forced to join - or else be unable to participate.

It's a collective action problem: you'll have to persuade millions and millions of "normies", who have no idea what's going on, or what internet privacy is, or what's broken about the system, and who don't care to learn, and won't listen to us - or you'll have to impose regulation. Those are the choices. The second seems more possible than the first. Us nerds saying "walk away" is idealistic; we will, and always will, get squished, because the corps have the power and most folks won't (ever) care.
