Earlier quoted context omitted.
Aha. This makes a lot of sense for Google. But the same websites show up in e.g. DDG (through Bing), as far as I know neither DDG nor Microsoft make a dime from ad-supported websites like Google would, why are these results not nuked similarly to what Kagi is doing?
Most other search engines train with a target of google or with some form of reward which is bootstrapped on google rankings. It makes Bing results implicitly have the same behavior as Google. DDG and others just use BingAPI so googles incentives pass on through.
If true however, it does go to show that Google is really a monopolist in the search space as well... and to substantiate this claim would go a long way into proving that.
