If you aren&#x27;t given a prompt that gets you to act in the way the advertising wants, its not a very effective ads. Lots of ads are better at doing that if you <i>don&#x27;t</i> know who wants you to take the action at issue -- its particularly true of political ads, which is why there are attempts to regulate disclosure for those, and attempts to obscure the actual interests represented as much as possible while complying with the regulations.<p>In any case, publications disclosing advertisers in content is an issue because the advertisement may be remote from the <i>particular</i> content, but the relationship with the advertiser may still shape the content. This remains an issue even where viewing the actual advertisements from the advertiser would reveal the identity of the advertiser.
