At work, we use Google Workspaces so that we have gmail and google docs and google sheets, and the "features" noted in this post have all shown up for us. That said, we were able to turn them off and haven't been bothered by them since. I don't remember the process being hard at all. That said, it's still something you need to do to have your settings not be the default settings, but is that necessarily any worse than any other setting you like to change away from the default?
I don't think you can turn them off as a free gmail user.
