When every corporation attaches the same fifty thousand words' worth of abusive T&Cs to every service they offer, consumers have no choice: they can consent to being abused (in this case waiving their legal rights), or go live in the woods where they don't need a smartphone or a credit card. As usual, our impotent, incompetent, illegitimate government has utterly failed to protect us in this regard.

Because when you signed up, you agreed to terms of service that said they could, just like you do when you sign up for pretty much any service.

Do you read the terms of service?

It doesn't matter if you have read them or not, because they could have changed the ToS 30 mins later to be something completely different and it is assumed you agreed to that too.
