Umm, I think this is more like "airlines vs passengers" when passengers read about "hidden city ticketing" in a travel blog, think it sounds cool yet haven't properly understand it, yet decide to go to town on it anyway.[0]
Since most providers are entirely at liberty to tell a customer they're no longer welcome, as a customer you have to be really really sure you want to own up to the provider as being an adversary, since you might end up needing another provider. For ever.
(Full disclosure: have been looking for, booking, and flying on less-than-entirely-legitimate airfares for a looong time. Have occasionally broken out in a cold sweat at an airport in some far-flung country on a dodgy itinerary when I think I've been rumbled...)
