This won't work, i'm telling you, companies will never allow this. What they should have done is to ensure companies warn people about the possibility of terminating the products they offer before the purchase, that's it. It's people who with their money support whatever practices these fucking greedy companies opted to try to dry you out of money. Just be honest and tell people what they are paying for beforehand, a simple "We reserve the right to terminate this game whenever we want without any warn for whatever reason" warning just by the side of it's price.
Btw, you wouldn't buy a car if it had a "2 year lifespan" sign besides it, would you?
