They would be representing their module is GPL when its not, obtaining
services by deceving people (3rd party support) and if they used _GPL
symbols probably violating the DMCA by bypassing a digital rights
system.

In practice we've had two cases we know about where someone tried this,
one at least was almost certainly an accident the other one the vendor
seems to now have fixed after the threat of acute bad publicity.

You could equally ask the same question about any other measure - its
no different to "I could shoot the shopkeeper and not pay", its an
incentive to behave, a way for developers to make it clear their code
isnt for stealing and without denying people the choice of what they
run. The reputable vendors on the whole not only seem to obey it but
actually put informative MODULE_LICENSE() tags into their code for
their proprietary licenses.
