Why? Tracking is not illegal. It's just tracking without consent that's illegal.
I have an alternative ideology to sell you...
we product enough to feed everyone.
I don't - and I am fully informed and prepared. A month into the cookie banners avalanche and I just started clicking OK without looking. Now I have the "I don't care about cookies" extension and that's it.
I think this question is very context sensitive. The way privacy questions are usually presented ("we want to improve/personalize your experience"), I don't think most people care. But when presented with actual outcomes of loss of privacy (e.g. the Cambridge Analytica scandal) people seem to care a lot. For most people I suspect there's a gap in understanding between how people think their data is used and how it's actually used. Whenever this gap is closed by a major scandal where "how the sausage is made" is revealed, there's often a strong reaction.
But perhaps the biggest indication that people do care about privacy is that ad companies are so reluctant to allow them to opt out of tracking. If (almost) nobody cares, what's the harm in having clear consent or an opt out?
That is: where you can’t track people without explicit consent, consent is as easy to not give as to give, and you can’t choose not to deliver the service or deliver a worse service to those who do not consent.
But if you assume the court decisions stands then if your business is based on tracking that means your business is based on illegal activities.
The only way out is to either change your business approach to comply with the law or go out of business. That’s no difference to many other activities that probably could earn money but are illegal.
