You trust them? How do you know this just makes you more suspicious and gives them more of an illogical basis for placing you under increased surveillance.
Sure I trust them. The moment it's discovered that they've failed to hold up their end of the bargain, they're out $30 x some significant percentage of the users of that service per month. That's not chump change (to say nothing of the potential class action lawsuit for utterly failing to hold up a contract while continuing to charge customers for the services stipulated in said contract).
We assume that we are entitled to some sort of protection because we've paid for a service, but that didn't stop these companies from unlawfully participating or turning a blind eye to unwarranted and unrestrained violations of privacy. If you believe some court centered process will protect you from abuse you are sadly mistaken. Of course it is no issue until the fascists come after you....
