A Facebook or Twitter-esque addiction algorithm is WAY better than a CCP addiction algorithm since the latter tries to socially engineer unrest and disillusion, on purpose, as a targeted act of Nakatomi-esque cyberwarfare against a totalitarian regime's rivals. The former kind maybe does so as an inadvertent externality, and with every reason to wager to a far lesser degree.
Meta won't turn up the heat on antisemitism and down on something the CCP doesn't like. It might turn up the heat on, I don't know, trans rights, and down on neo Nazis, but it's much more benign dystopic info filtering than an actual "what will destabilize the US and fuel stochastic terrorism and civil war?" agenda (which is against Meta's best interest).
