Devil's advocate argument: if they were giving you something in return, and that could be cash, but it might also be "you can have this content for free".

In the UK a few news sites have changed cookie banners to "you can accept and see this stuff for free, or you can sign up for a subscription, which would you prefer?". It's the only time I hit accept (and then clear browser history).

If blanket preferences from browser signals became the norm, a segment might open up where you would configure preferences and a data broker would make sure you get something in return for your data. At minimum it might force paywalled publishers to consider that as a "lite" subscription option.
