"Fair" isn't well-defined. Is it "fair" if Amazon results are seen as "more trustworthy" than a random new startup web store? Even ignoring SEO manipulation of any rules publicly believed to exist, that's the default outcome for things like PageRank.
Going beyond sources to conclusions, given LLMs aren't search engines and do synthesise results:
Politically, low-tax advocates see it as "fair" for people to take home as much as possible of what they earn, high-tax advocates see it as "fair" for broad shoulders to carry the most and also for them to contribute the most back to the societies that enabled them to succeed.
Is the current status of Americans whose ancestors were literally slaves made "fair" by the fact that slavery has ended and all humans are equal in law? Or are there still systematic injustices, created in that era, whose echos today still make things unfair?
Who has the most to blame for climate change, the nations with the largest integrated historical emissions even where most of the people who did the emitting have died of old age, or the largest emitters today?
And so on.
