You are mistaken. Social media and things like youtube, just like elections, provide the appearance of power and choice, but just safely let people to let out pent up emotions. Then they safely contain it without it being spilled to the real world to a certain extent, at the same time give the people who participate in them a certain feeling of "doing something", a fallacy that even I am committing right now while I write this comment down..
As Noam Chomsky said "The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum".
We already know that youtube and other media like reddit even HN "strictly limit the spectrum of acceptable opinion", and as you said, they also allow very lively debate withing the rest of the spectrum..
Like January 6th? Safe containment indeed.

Which results in an ever increasing number of extremist refugees. The Fediverse appears to be growing consistently and I think the systemic mechanisms that are concentrating extreme viewpoints there should be cause for concern.
On the plus side, if a particularly interesting video is removed from YouTube you can often find it mirrored there.
Also, YouTube (and Google in general) manipulates search results. E.g. in Russia you're fed by force with Navalny's channel. If you block his channel explicitly, YouTube starts to show you one of the thousand clones of it. Or other content with similar views. While content that contradicts the YouTube censorship policy will be well hidden from view.
It's not a freedom of speech.
I understand that US has the strongest propaganda and state of the art brainwashing techniques. So the usual reply is something like: "But it's the absolute truth! Anyone trying to refute it is a bigot!" But I know the only truth: there's no absolute universal truth. Imagine what science would be if it would be disallowed to refute theories?..
US bigotry is something resembling a religion: "We know better how people in country X should live!", "We know better how all the world should view same sex marriage!", "We know better how the country Y should be governed!", etc, etc. But the point is that most of the time people saying this don't know where the country is located, it's culture and traditions, why the people live the way they live, do they like it or not, etc. They just sure that everyone would be happy to eat hamburgers, drink Coca Cola and have Disneylands everywhere. It's such an arrogant dumb view, but it's ingrained in every western person by the best media and propagandists.
