The entire targeted advertising industry is basically a progressive tax.

The "social contract" is that many services are fully or partially financed by advertising. Rich people produce more ad revenue (because they spend more), but they get the same quality of service, effectively subsidizing access for the poorer part of the population, who couldn't afford it otherwise.

If we break this social contract down, companies will still try to extract as much revenue as possible, but the only way to do that will be through feature gating, price discrimination, and generally making your life a misery unless you make a lot of money.
