Up until ~2009MY cars, if you didn't pay for OnStar, they never activated your vehicle and they would never have access. I think it was mostly a liability / strategy decision rather than a cost one, but you can imagine people calling up and begging OnStar to start a subscription when they need it and then cancelling immediately after. Or trying to subscribe if their car was stolen to track it down..
