The reason you're supposed to keep clear of the ILS critical area is
because your airplane can affect the glide slope beam. The presence or
absence of somebody in the tower doesn't change the physics of how
microwaves interact with metallic bodies.

Thanks, but that wasn't my question. In fact, you snipped my question
out of the 'quote' which you included in your response.
