You seem to have an assumption that people aren't competent to decide their own ideas and only follow what they see the most of. That's true to a large extent but you'd have to ban all religious information too if you really meant it.
This whole idea that false information needs to be suppressed only became popular after Trump's election win. People needed an excuse to explain that because they couldn't imagine so many normal reasonable people could possibly vote for him. The only explanation must be that they were not very intelligent and got suckered by external influence. That's a pretty arrogant viewpoint and its conclusion - censorship - is pretty naive direct action that ignores their legitimate concerns as well as the obvious horrible side effects that come with censorship. Since when did "these people aren't smart enough to take care of themselves, let's tell them what to do because we know what's best" ever work on a large population who are different from the "bosses"?
