I think that on some versions of the Commodore PET, you actually COULD
damage the machine via software!  As I understood it, by (im)properly
programming the CRT controller chip on the fly, you could turn on the
video monitor's horizontal output transtor in the middle of a retrace.
This is quite likely to cause it to blow up.

Such oddities aside, that kind of hype seems pretty sleazy.
