There is an interesting project America's Digital Shield that studies these practices (https://americasdigitalshield.com/). They capture "ephemeral" content from search results and social feeds from volunteers, with a balanced distribution of the political spectrum.
Basically, the idea is that none of the content we get fed from tech giants is unbiased, even search results are manipulated to affect people one way or the other, especially when it comes to politics and elections. It's pretty upsetting once you understand what's happening.
"Claude's fault."
Watch for more fuckery during the current US election season.
