I mean, that change _could_ be made, but why on earth _would_ it be made? It would largely defeat this portion of the GDPR. Who actually wants that change beyond advertising companies?
Why would it not be made? Each person has agency in the decision to share their data. If it is indeed _my_ data then _I_ should be able to choose to sell it or move on. Forcing a companies hand, I predict, will just move more content behind a paywall, decrease access to legitimate information and further fringe conspiracies.
But this thing where big sites say "data or else" isn't a proper negotiation. It's a contract of adhesion, and those get regulated for good reason.
If things get moved behind expensive paywalls, that's a shame. But if there is more truely free access, or content behind paywalls that charge as much as an ad is worth, that can be a net benefit.
