And if companies don't want to do it, that should be easy to regulate though. Requiring a human centric appeal process even if it has a fee, and prohibiting blanket account bans (if you get banned on gmail it doesn't affect your android and play store accounts, for example)
There are other provisions that I consider important like not being able to reuse email addresses and requiring the forwarding of email for at least 6 months after any account termination (getting banned from your email address can have disastrous consequences)
