I know HN takes a pretty critical view of "mainstream media", but I believe a world in which NYT/Wired/WSJ and similar have been successfully run out of business will be a very different one. They are among the last to have the resources to devote teams to investigate issues. There's nobody capable of replacing them.
I with there were an Adblocker that takes this responsibility serious, blocking maybe video and ads over content, but not static images and text ads.
For the commentator saying that "most consumers don't care how carefully ads have been selected. It still is an ad and we don't like any ads :)" I can only answer that problem started when you called yourself a "consumer". We need more citizen, less consumers.
