Unfortunately, there kinda is.

This is what Tim Cook said about govt agencies wanting a backdoor - https://www.youtube.com/watch?v=BZmeZyDGkQ0 - right around 4:25.

When I buy an Apple product, this is part of what I think Apple does to protect their customers' privacy - No matter what, not even if the govt says so.

Now suddenly, we're back to talking about whether we can trust Apple after they expressly told us not to trust ANYONE including Apple and why that was such a good thing.

For me, the slippery slope is exactly allowing this sort of transaction to be called "buying".

And yeah, when people lost access to their zune music, or their steam stuff, they did get upset.

Mind you, I would not outlaw the transaction. But calling it a "sale" is false advertising in my book.

The problem isn't that they make decisions about what the device can and can't do before the moment of purchase. As you correctly pointed out in another comment they made the implicit choice to not ship it with the ability to make pizzas and everybody thinks that's fine.

The problem is that they (have the ability to) continue to make those decisions afterwards. You could have "known" an iPhone could run Fortnite at the moment you bought it and then after you received it in the mail discovered that they had decided you were no longer allowed to do that.

You could then say "well I bought it knowing they had the ability to change anything at any time" but I'm not sure I agree that you can give informed consent to a blank check.
