I'm not saying that the terms can't be more transparent, because they absolutely can be.

But if you have become aware of this practice and you continue to participate, you have de facto agreed to it. You can of course agree to the terms and continue to criticize them, but you don't get to sign up for a soccer game and then claim that the rules against using your hands don't actually apply to you. If you don't want to face the consequences of how distributed services like this fundamentally work, don't use them.
