This again? Come on. When you sign a contract most of what can or can't happen is already spelled out. You don't sign a contract unless the stuff you're getting back in return outweighs or balances with the stuff you're willing to giving away. A reasonable person walks into a contract like this with a lawyer and knows exactly what they're getting into. This isn't the same as signing some credit card application where you don't get to make modifications to the contract.
