 You get a couple of government executives working for this titanic, multi-trillion-dollar, hyper-politicized government, and they sit down with the guys that run social media platforms, and there aren't that many of them because a couple of big companies dominate this area, and they start saying, hey, we have some thoughts. You need to start suppressing people that disagree with official truth. The Ministry of Truth has decided that X, Y, and Z are true, and anybody who says otherwise, we think you need to shut them up.
