I agree. I think the main problem is personalized advertisement that incentivizes companies to record as much data as possible. I'd prefer if they worked like they do in print magazines. Every reader sees the same.

Lets say I'm reading a laptop review. Show me adds from the laptop manufacturer or of websites that sell said laptop. People reading the review are likely in the market for a laptop so it makes sense to show it. At most you could probably narrow it down to the country so a German doesn't get shown a Best Buy ad but thats as far as I would go.
