I sense you’re focusing on the trivial and missing the wider point; closed proprietary clouds are not good for consumers.

Yeah, users are given prior warnings about the closure of some services and yes, data can sometimes be shifted from one walled garden to another. But for the average user, such hurdles -regardless of how easy they are for us techies- are major deal breakers. And thus these “features” are often little more cleverly deployed vendor lock-ins.
