In the sense that their devices are not free.

The fact that you don't want to use it that way is hardly relevant to the question of freedom.
Listen, i'm not saying they should spend a bunch of time engineering a solution to support this use case. I'm not saying they should aid people in doing it in any way. But that's not all they're doing. They actively expend resources to thwart people controlling their own devices. It is their corporate policy not just not to support this behavior, but to make it technologically impossible. That is the key point.
If Apple had just said "if you modify the OS, you void your warrant and you're on your own - we offer you zero support", i'd be totally fine with that. Personally, i'm not interested in modifying my device at all, i'm happy to leave it as is. But to go out of their way to make it impossible to do that? That's anti-freedom, no matter how you slice it.
