You're confusing a CONTRACT, which is legally binding, with an AGREEMENT, which is not. You can, at any time, go back on your agreement, and if you feel cheated, you can have it investigated in good faith.
A contract is a legally binding, obvious, minimum bullshit document between two or more parties, and bad contracts will also be sorted out by the law, but if a contract was done properly, YOU are the one who's gonna end up paying for withdrawing from it - not the big business.
Until the EULA and ToS say, in simple terms, what you're agreeing to, and they're legally binding documents, they're not, and you can easily take people like Blizzard, Valve, Ea, and whoever the fuck else - your local grocery store owner - to small claim's court, where the judge will rule in your favor after an hour of talking, then bonk the business on the head and tell them to stop being so fucking greedy and stupid.
