No, and I submit that this is at least arguably something wrong that TiVo is
doing. Note that Microsoft does this too when you buy an Xbox. It has
nothing to do with the GPL.

I agree, however, this doesn't restrict the user in ways contrary to the
GPL. The GPL does not say that you have to be allowed to modify the Linux
running on some particular piece of hardware because that is a legitimate
authorization decision. TiVo not letting you change the software is the same
as me not letting you change the software on my laptop.

This is solely a right against copyright claims. You would be correct if
TiVo were going to sue you for violating some copyright they hold in the
hardware or software if you modified the software.

Yep, but that has nothing whatsoever to do with the GPL. The exact same
argument applies with the Xbox. It's about whether authorization to modify a
device should or must come with buying that device.

The GPL was never about allowing you to load modified software onto hardware
where the legitimate creators/owners of that hardware say, "no, you may not
modify the software running on this hardware".
