There are many things that are “relevant”. If you have an interest in retro Casio watch collecting, showing you review videos for retro Casio watches would be relevant. But … would it get you “engaged” as much as showing you biased political videos with outrage inducing clickbait titles? Facebook’s algorithm is like an orchestra conductor. By its choice of content it chooses to show Facebook users, it guides the actions of its users. It’s main goal is to guide its users into sticking around for as long as possible - which while is somewhat manipulative, most people aren’t too bothered by that. Unfortunately their algorithm’s choice of content has been discovered to have other more unpleasant side effects … and Facebook isn’t willing to sacrifice profit by having its algorithm suggest stuff that’s just as relevant to a user, without the unpleasant side effects, but less “engaging”. In the shorten 60 minutes interview, I believe the whistleblower mentioned that Facebook leading up to the 2020 election actually clamp down on its algorithm fearing things could going south but lifted the measures after the election was over … then we got 6th Jan 2021.
