An Xbox 360 owner is using a contractual technicality in the Xbox Live terms and conditions to press a legal claim that Microsoft owes him $500 billion.
"I see a lot of friends and family who get pushed around and walked on, who have causes of action against them, but they choose not to pursue those causes of action. Lots of people are victims of torts... few of them actually sue over them, but that doesn't mean they can't," he told seattlepi.com. "I, on the other hand, will not let people push me around, just because I've already filed a bunch of claims, already."
So basically he's doing what the big companies do without the money or the power. Change the contract to his will and assume that no response means he wins. It's definitely a very interesting point he's making, even though the tree will bear no fruit.
