If it's not unlimited then don't call it that. If the company expects users to not do certain things, then state that in the contract. If you call it unlimited and it's not really unlimited and depends on what the company feels today, then it's just false advertising. In my organization if I were in charge of contracts and pulled something like this, I'd be out of a job and my chain of command would be under review. This is simply unprofessional.
