Can I opt out of cyberstalking, have my dossier removed from your servers, and just see ads relevant to the site I'm visting? You know, just like newspapers and specialized magazines do?
This is the core point you’re missing. People here are talking about the industry as a whole. Not your ethical internet ad firm or you yourself.
The industry. Not you or your situation.
I’ve worked at a “marketing analytics solutions” company before (shudders at the memory).
I had access (was a data processor) to 60 million UK people’s info on their mortgage, email address, age, marital status, car make/model, likely holiday destinations... etc etc.
What we did with the data doesn’t matter. The fact it does is exist and is hidden from the customers view is the problem.
