Under what jurisdiction am I allowed to create a policy to use whatever I want however I want? Playing the devils advocate I have to assume their lawyers didn't

Under what jurisdiction am I allowed to create a policy to use whatever I want however I want? Playing the devils advocate I have to assume their lawyers didn't just pull this out of their asses? Now I'm making a policy that I'm allowed to (ab)use Googles services however I want. They can find the policy themselves. God I hate Google.
