A lot of us have other stuff that it's unclear how we migrate. YouTube premium subscriptions, Google Voice, YouTube channels, "sign in with Google", Google play purchases, the list is endless...
Some of it includes pricing/specific products you can't sign up for any more, either.
I'd be happy if there was a way to migrate my account as is, with everything in tact to a regular@gmail account.
The article specifically states you won't lose access to anything you've paid for and you'll still be able to authenticate with that account. You just can't use it for mail, calendar, drive, etc. Just repoint your email to another service, export your calendar, and move your data somewhere else.
Considering GSuite is pretty much hot garbage in 2022, they're almost doing you a favor. Seriously, this is good for you. It'll be like you've been transported to the future!
in what way is gsuite garbage ? granted, i mostly just use gmail. but after a few years at [major company], gmail seems light years ahead of anything they use
