Apple's ToS should be readily indicative of anyone using any of their products that Apple's perspective is that you don't own anything and they can do whatever they want with anything you do with their products. As the author points out you clearly don't own free access to what you've purchased.
The last thing I'll say is that it is fantastic advice to not purchase Apple in 2025. You can only be certain that this won't happen if you avoid them. I actually own a MPB, with receipts from purchase, that I had to purchase a bypass for when the device was enrolled in MDM by a family member that Apple has MDM locked and refuses to remove from iCloud.
Avoid Apple, that's the best advice. If you can't avoid Apple, minimize your footprint and make sure you're a good boy or girl else Tim Cook will steal from you and hide behind some bullshit first line support tar pit and an army of lawyers if you do happen to decide to threaten them.
