But you don't care enough to stop visiting the sites themselves? As if the "dossier" can't be built without ad code?

I can't think of any good reason to forcibly separate a website from its ads. Any arguments against the ads are just arguments against the website, and I think attempts to argue otherwise are just trying to have your ad-free cake and eat it too.

Somebody paid and is paying for your visit. For the website itself. It's somebody's labor. If they didn't want ads, they wouldn't have put them there. Clearly you've gone to some length to convince yourself that you're justified in your actions, but you're not. You're taking something for free that the creator intended to be paid for.
