What does it prove? All social media are concerning and owners can manipulate people and I would say even change the outcomes of elections, just by fine-tuning the algorithm. Recently I've noticed that YouTube is sunsetting one of my favourite YouTubers. I watch him every day and every day I need to find him manually because he's not on the first page. If the algorithm was tailored to me, it would find that this guy is the only one who I watch every day.
