Increasing the echo chambers of conspiracy theorists, extremist and with that influencing things like elections seems quite the impact to me. All these mega corporations could’ve tried to limit these things, but probably that would’ve looked bad on their balance sheets.
Add to this the insane amount of data harvesting they do on their users and in general just making every damn platform worse from year to year while only looking for ever more profits.
I grew such hatred for this man in the past years I wish he would just ruin himself and not hear a delusional thing from him ever again.
