If that was the point then it doesn't apply to me. I don't go to Facebook or Youtube or even Google for my sources of information.
I'm not sure I agree with this. These tech giants (among others) are shaping the culture, popular opinion, and the overall national discourse whether or not you participate at the origin. So I don't think one is able to avoid the problem.
Many people blamed Trump's election on Facebook analytics targeting people with what would make them vote for Trump. To say that the media filters things is not new, nor is it even something only those on the right are aware of. Everyone is aware of it, and everyone only seems able to see the filters when the filters point away from what they believe.
Here, you are confusing two arguments, probably because I have not carefully defined terminology. Tech companies obviously must filter content. That is their main purpose, to cut infinity down to ten or twenty things that might be of interest to you. Those who complain that pro Trump messaging is shared too freely are arguing that the filters should not be blind to what the content is. Rather that, with certain specific types of content, the filters should suppress more strongly.
On the flip side, those who are trying to share, say pro Trump content, have noticed that their reach is being curtailed. The filters are not acting impartially or in alignment with the stated terms of service.
Those in the first group are arguing for more censorship; those in the later group are claiming that they are being censored. The narrative is "there's nothing to see here". The problem is, you cannot appease the first group without the second group providing damning evidence that the narrative is wrong. So one has to be very careful to claim that the censorship is only catching conspiracy theories and bots and if too much of a fuss is made about something, it can be uncensored claiming it was an honest mistake.
But it is not simply across political lines. It is anything that does not fall in line with the narrative. The link I posted was an attempt to illustrate this. Bret Weinstein is a biologist, Robert Malone is the inventor of mRNA vaccine technology, and Steve Kirsch has been investigating adverse reactions to COVID vaccinations. In the first portion of the discussion they draw attention to how big tech and the media are censoring anything that does not comport with the "vaccines are 100% safe and effective" messaging. They also talk about many other things with regard to how the vaccines are intended to work, what things we are starting to observe, etc. The truth of their claims is not at issue. What is of relevance is that in order to get to the bottom of these things one must be able to communicate different views, share data, and generally engage with all the conspiracy theories (and reject most of them) to distill out the truth. Tech companies and media suppression is acting on the presumption that they already know the truth of the matter and can safely remove troublesome content. To draw parallels with the dihydrogen monoxide hoax, it would be like tech companies removing any discussion or information revealing that dihydrogen monoxide was just water or downplaying the severity of its impact on the basis that we already know dihydrogen monoxide is so dangerous. This approach perpetuates and entrenches errors by removing those who would correct the discussion.
Incidentally, YouTube has removed the video since I posted the link. I suppose they are making my point. The video is also available here
