I agree. For example, a patent might impose a further restriction. The GPL
was clearly meant to foreclose that. There are any number of other ways of
nasty, subtle ways to impose further restrictions, and the GPLv2 meant to
foreclose all of them.

Right.

The response to this argument is that it is mind-bogglingly obvious that the
GPL doesn't mean that no *authorization* decisions can stand in your way. It
didn't mean that I couldn't keep the root password to my server secret even
though that denies you the "right" to modify the Linux kernel running on it.

Some entity has to decide what software runs on any particular piece of
hardware, and it was never the intent of the GPL to specify or limit who
that person was. This has been discussed many times over many years, longer
before Tivoization was even thought of, and it was agreed that the GPL
didn't foreclose authorization obstacles to software modification.

Why doesn't Linux allow a non-root user to install a module or change which
kernel the system runs? Doesn't that limit the GPL rights of all non-root
users to modify the GPL'd kernel software on that machine? OF COURSE NOT.
