I don't think google/twitter/facebook are any different than tiktock. Honestly, I'd love to see something done with these companies too, since it's clear that making microphones available to anyone, whether they are a human or a script, just leads to noise that overwhelms any expert level signal on world events or domain knowledge. I'm not sure what can be done at this point, though, it's like pandora's box has been opened. Now that the playbook is there, the internet is legitimately polluted for good. There will always be some other social network to trivially exert manipulation on, since humans are just wired to give into this tribalism as a species at the end of the day.
