They'll rent you more iCloud space when you fill up the SSD. That's good, holistic customer service.
I'm not sure if you're being sarcastic, but what you're calling "good, holistic customer service" is more commonly described as "inventing a problem and then selling you the solution".
That doesn’t work unless you’re actually able to offload stuff from disk, which is only the case when you store stuff in your iCloud Drive / photos / etc.
Case in point: the AI models can’t be offloaded to iCloud.
