There is no real evidence that the Russian campaign on Facebook was effective at all in 2016. I believe the entire campaign wasn't necessarily to effect the outcome, but to sow doubt on the outcome. Putin just wanted chaos. The real poll shift came when Comey made his statement on the Clinton email server within weeks of the election.
I'm 100% in favor of Facebook policing things like the "Plandemic" nonsense, but that's not what these companies are asking for. They are essentially asking for a partisan tilt to the platform...when the platform itself (imo) should strive to be a neutral party.
Alas, how do you define neutrality? What happens if Plandemic hypothetically becomes associated with a partisan party? How can Facebook be neutral there?
I agree they should try to be neutral, but I don’t know if neutrality is even possible in a lot of cases.
And of course, once actual crazy people control the government, who is going to install and maintain the guard rails?
