I suspect that its more about a slick salesman selling a system to the CG owners and promising things that they knew wouldn't work. I stayed at a FHU CG in Virginia once that advertised free WIFI. Yes, it was free, but no, it didn't cover the entire CG. As it turned out, it needed repeaters. Since I had nothing better to do, I walked around the CG with a laptop, trying to connect. There was a fan shaped area starting at the office and connecting at spots that formed a rough semi circle. Beyond that line, no WIFI.
So for the remainder of the contract, they chose to ask folks if they needed WIFI and assigned spaces accordingly.
And I got a couple of free beers on the porch at the office. :)
