Ask HN: Is there a cloud-based email service where one cannot be deplaotformed?

I use Gmail. While I don't think it's likely won't ever be deplatformed for my personal behavior, you never know these days I could get deplatformed for something stupid I did years ago, because I piss off the wrong person on the wrong day, or simply because some bot goes on a rampage. Are there any cloud-based Gmail alternatives where one doesn't risk being deplatformed? I could self-host, but that comes w/ it's own set of risks. Basically, I dreaming of an email account that carries zero risk of being lost, short of an external even like a natural disaster or the government itself declaring my email address to be a national security threat.
