Privacy is only a myth. If they want to copy and give something whether it be to the government or whomever there is nothing you can do because odds are you won't know until it's already too late. Then, once you're implicated in something or find out about it there's not much you can do unless you just happen to have a wheelbarrow full of money sitting in your living room that you can use to hire a lawyer to help you at least lose in style.
