> To sell ads, websites need to be able to show what demographics of people have clicked on ads
Not really. You just need to look at any normal billboard; advertisers bought that billboard, even though it knows nothing about demographics or "attribution".
Tracking just makes advertising more cost-effective. To the advertiser, not to me. I'm not an advertiser; I gain nothing from the cheapness of advertising. It makes no difference to me whether an ad is targeted or not; I don't want to see it. Especially if it writhes and wriggles distractingly, or autoplays video.
