@bayo @parismarx I don't find the echo-chamber discourse particularly useful. You could accurately describe all of the biggest media platforms as echo-chambers (social or otherwise). Reddit is an echo-chamber, BlueSky is an echo-chamber. Mass media itself is an echo-chamber.
All these forms of media serve the function of re-enforcing an ideological dogma, be it tech-bro Libertarianism on Reddit, Groyper fascism on X, or dead-end lesser-evilism on BlueSky. They are all adept at whipping up a McCarthyite hysteria against dissent.
The quality of discourse on all these platforms is trash. Anybody with actual principles is quickly censored, throttled, shadow-banned, flooded with abuse, or chooses to keeps their mouth shut to avoid retaliation. It turns out we need independent platforms which are willing to punish the majority of little Eichmanns instead of coddling them for ad revenue and reducing themselves to the lowest common denominator.
