The ISPs don't necessarily want to annoy customers on someone else's say-so... I know they get a bad rap for annoying customers most of the time, but they usually do value having customers and aren't keen to have this merry-go-round of churn that receiving these kinds of notices will bring.
I do agree that free wifi operators have some serious issues ahead of them, and that's a very bad thing given the state of the industry (just starting really in NZ) and how important internet access is becoming in NZ.
