Wired reports that Meta's advertising business is absorbing a measurable hit now that European users can choose a less personalised experience. The mechanism is not mysterious. Targeted advertising earns more per impression because it is better at predicting what a viewer will click or buy; remove the profiling, and the same inventory sells at contextual rates. When a large share of a market is given a real choice, some of them take it.
What matters is that the choice became real. Europe's consent rules always said personalisation required permission, and for years the permission was extracted with banners designed to make refusal a maze. Regulators pushed back on the 'pay or consent' workaround — the model in which users either accepted tracking or bought their way out of it — on the grounds that consent is not freely given when the alternative is a fee. A genuine no, offered without friction, produces a genuine decline in signal, and therefore in price.
The second-order effects are the interesting ones. If opting out of personalisation is now visibly expensive for the largest ad network in the market, it establishes a floor under contextual advertising: the gap between profiled and unprofiled rates is exactly what a privacy-first competitor can sell against, and exactly what an advertiser can point to when arguing that the premium for tracking is not worth the compliance risk. It also gives European regulators a number to use, because the cost of the right to refuse is now measurable rather than theoretical.
Expect the pressure to move to the interface rather than the substance: how prominently the no is offered, how many clicks it takes, whether the fee-based alternative survives the next court ruling. Meta has every incentive to keep contesting that ground, and the DMA gives it a venue.
The uncomfortable finding for the industry is that personalised advertising was never priced as a privilege. It was priced as a default, and defaults are worth a great deal only as long as nobody is allowed to leave them.
