You're again confusing legal terms with the intent. The legal terms
provide an indication of the intent, but the preamble, along with the
free software definition it alludes to, do an even better job at that.

That said, the letter of the GPL explicitly says that the act of
running the program is not restricted, and that this is outside the
scope of the license. It's a copyright license, and per US law,
running software is not regulated by copyright; this is not so
elsewhere, and local interpretation indicates that the intent of the
license is indeed to grant unlimited permission to run the program and
modified versions thereof, based on the free software definition.

But then, when someone says "I won't let you run modified versions of
this software on this hardware I'm selling you", is this not a further
restriction on the exercise of the rights granted in the license?

And, per the spirit, if the manufacturer can still install and run
modified versions of the software on that hardware, is it not failing
to comply with the spirit of passing on all the rights that you have?
