Newspapers get monetized via ads. Google search being the prime entry point was "preventing" clicks by summarizing articles. Also, Adsense being the biggest kid in the block could set prices due their position as a king maker.
Hmm close but not quite, IMO. That all happens, but this article is about Google's tendency to actively defend their monopoly over the "Ad Exchange" market, which is how publishers (newspapers) are connected to buyers of advertising space (advertisers, both brand advertisers like Coca-Cola and performance advertisers like mobile games). It's nothing complex, just the same ol' man-in-the-middle racket that impoverishes both sides as they skim off the top, confident that neither party can go to a competitor.
They very much are trying to muddy the waters here, so no hate for the misunderstanding. This is the third active anti-trust suit they're currently involved in, after all! Also, as always: AFAIK ;)
Craigslist is largely a ghost town these days: a lot of that stuff has moved to Facebook Marketplace, Ebay, etc. for selling stuff, and dating apps for the "personals" stuff.
Basically, decades ago before the internet, newspapers served a role in facilitating communication between strangers, in a rather poor fashion. Individuals didn't have the money to have their own printing press and distribution system, so they had no way of contacting people unless they already knew their telephone number, or knowing what others had to offer. So newspapers had the "classified ads" section so people could spend a small amount of money and run a very tiny ad in the weekly newspaper for others in their town to see, and it was easy for the newspapers to just add a few extra pages with this stuff at the end. The internet simply made this all obsolete.
If the newspapers had been really forward-thinking, they would have created first the social network services and become dominant there before MySpace, Digg, and Facebook came along. But it took them ages to even start thinking about anything besides a business model dependent on printing newspapers.
