Well that depends on where and how you draw the line.  They could have a
bootloader that would allow you to put unsigned ROMs on the phone, but
would erase everything, while still having a non-destructive update
mechanism that requires a signed binary.  They could argue that an
unsigned binary voids warranty (as the GPLv3 allows), and their
mechanism for knowing if someone broke the OS is that their
non-destructive update requires signing.

That would satisfy the anti-tivoization and be within the limits of the
GPLv3, while still causing a problem for the FBI in this particular
