I’d say that the conclusion there should be that you shouldn’t need an account to use an expresso machine. I’d also point out that an expresso machine isn’t a data-harvester.
It was the newest non-computer/phone/tablet gadget I could think of that required an account to be created. You can access it and use it via an app once you have created an account.
If you don't want what you term a "data-harvester." then the simple solution is don't use MS products nor Google nor Apple nor pretty much any mainstream "computerised" devices.
