I pay $11 / mo and have all of those things. GSuite/Workplace doesn’t run any ads or extraneous tracking, their corporate customers would never allow it.
I used to, before leaving for fastmail. But it's a joke to suggest that you get any meaningful support for your money. And I don't think that my account would get better treatment than a free one if they decided to delete it for some reason.
I run a basic GSuite organization and the two times I've had an issue with the service, I literally had a representative on either chat or phone support within minutes. It was a very pleasant experience.
Happy to spend my money on that. They did have to transfer me twice for a technical issue, but that was resolved too in the end.
I had a google suite account (with one email user) for years.
I had used the account to purchase stuff on Google Play. I wanted to close the GSuite organization account but retain the purchases. Either by transferring to another (disposable) gmail account, or by somehow closing the organization account but continuing to be able to log into other parts of google using a now-third-party email addresss. Or a refund. I don't know what options were available, that's why I contacted support.
So this was a transactional support request, not a Q&A. I did get through to a chat support but their answer was pretty much "I don't know, check the support forums".
I'm not trying to make my point about the situation, more about the customer experience I got for trying to ask what I imagine is a fairly common question.
(I feel like an idiot for spending money on DRM, but different story)
Your point is well-made about the level of support you might get from a Google rep. The answer they should give is that Play store purchases cannot be transferred to protect the IP contracts with sellers, otherwise there could be a potential for an aftermarket on Google Play account assets. I know some people at Google understand that, but I doubt that's in their support playbooks.
So it appears there is no one-click or Google support method for migration to a personal Google account and you cannot ever have a Google account with the same email address except for reactivation of a Workplace subscription. You can move virtually everything with Takeout and use account sharing features for the rest (so long as you have a small family…).
