Censoring is peripherally a problem, but its more a symptom of the way the fedi is so easily manipulated by just a few players who arent even neccesarly popular (since one person can control 1000 accounts without any real effort).
But sadly the problem seems to be worse just you hear about it less becauseso many people are censored you just wont hear it.
I actually wrote a white paper ill be presenting (hopefully) at AGI-25 on this topic (ethics in AI and I touch on the social media problem). I even started a whole non-profit that is quickly gaining speed to help address it. I tried doing this in a fedicentric way but the toxicity was too much, so this time I'm attacking it from an AI/AGI centric way instead.
I can share the first of the two papers (the second has the concrete solutions).
