Yeah i started to notice this as well. Also a ton of nsfw stuff nowadays seems to not show up anymore. Duckduckgo is even worse through. For what ever reason Yandex gets better results then google and duckduckgo. Not a fan of yandex in general though.
I absolute despise ads but they are a necessary evil, it can be implemented well if it is not done intrusive and doesn’t take up more space then the content it self. Also if it are mostly scam ads and such they might as well not have ads at all.
