I did not say anything about the content of articles, my comment was entirely about ads. If the article contains some topic and the ad targets that topic, the ad is not creating any new bubble. If the ad targets the user specifically because the user belongs to some group then ads are influencing specific groups in specific ways and forming new bubbles advantafeous to the highest bidder.

An ad for something men would like on a men's magazine or website targets men because they are already visiting a men specific content. An ad about the same thing on a random news site because the user is believed to be a man influences the user and other similar users to be influenced in the same way, even when they're not interacting with content specific to their membership of some group. This seems harmless but in reality the groups targeted are much more specific. So you may have those ads targeting "white men between 25-30,with college degree and living in an affuent neighborhood" , so in reality you now have that specific micro group being influenced differently, forming new bubbles. Men who don't also fit that criteria are not targeted, and are not influenced to buy nice undies. Replace undies with other more nefarious things (e.g.: food, medication,housing,job opportunities,etc...) And you can appreciate how ads are essentially micro-segregating people into bubbles based on statistical presumptions. Now if a usee visits a content,ads relevant to that content make a lot of sense. The problem is the user being targeted when they don't interact with relevant content and users interacting with relevant content not receiving relevant ads (e.g.: spouse reading about a gift for her husband won't see the nice undie ads).

Ads affect much more than what we buy, they affect out associations,peferences and views on subject matters. Non-consensual surveillance (stalking) should not be used to influence very specific groups of people. Now, I don't get why you have a problem with that?
