I recommend Jaron Lanier's "Who Owns The Future?" [0] on the subject. Trading data for services is not an unreasonable mechanism for value exchange,
a priori, and arguably better than nothing at all (the social externalities of "engagement algorithms" notwithstanding).
Rather, I think consumers are getting a poor exchange rate, not least because they have very little agency or transparency into the nature of the transaction. It's all or nothing: cede massive economic power to a small number of centralized corporations and enjoy (admittedly significant) trickle-down utility value; or, live as a quasi-Luddite and eschew these services entirely [1].
It's also worth noting the hidden costs behind the scenes: the massive power of data consolidation, and the accompanying "winner take all" dynamics, creates near-monopoly power in which the centralized networks (Amazon in particular) can dictate terms and prices, usually through the supply side rather than the demand side as was done by trusts and monopolies of old. (This also isn't new to internet services: the centralization of purchasing data through debit/credit cards pioneered the model.)
Lastly, Lanier likes to point out the curse of normalizing the price of "free" for software and services: while consumers obviously prefer it, every consumer is also a producer in one way or another, and so will find when it's their turn to sell some digital service / creative work / non-excludable good, the market is largely intractable to actually paying for things. The "surveillance capitalism" model crowds out other business models in many cases, making a small number of centralized winners the only players with the economy of scale to make money on "free" services.
