Diversity is provided by friends and family. Trusted human beings. Not the highest bidder in the auctions for our attention.
Also, without advertising, search engines and the web would be a lot more trustworthy than they are today. When searching I used to get many real websites created by humans, now I see ad-funded AI-generated utterly worthless SEO spam. Advertising is literally the root cause of the enshittification of the web.
Limited number of family and friends and their limited exposure to the products they have personally experienced is too limited for me. I would like to atleast check out what is out there. Then do research and then buy. Don't project your personal way of doing things onto others.
