(Mind that this isn't about Meta in particular, it's just that Meta has been found in violation of general regulations, which are now enforced.)
I would rather Google and Facebook have an financial interest in keeping that data to themselves, than having a financial incentive to sell it outright.
Also, behavioural tracking is by no means the only road to advertising. We have managed to do this for centuries with much less intrusion and risk.
They used to not build profiles... and we had the most awful ads served... and performing search resulted in pages upon pages of results we're not interested in.
Why do we have to nuke everything and sow the ground with salt, just because some paranoid individuals want everyone to suffer their delusions? Especially, when the governments have more and more power to spy on us?
But, I guess, we won't agree on this.
That doesn't negate the fact that targeted advertising is drastically more cost effective for smaller companies. It's drastically more valuable for sites that provide advertising space. It's a win-win for almost everyone involved.
We're talking about ads, not recommended content here. These are two very different things. You conflated them, to make an argument that has nothing to do with the topic at hand.
