How else is the mainstream supposed to spin reality? Entertainment giants used to more easily create the illusion of consensus, but web platforms like YouTube completely mess with their power by showing downvotes.
Suppose there is a YouTube channel about how a minority in a certain country is discriminated against. Given what we know about discrimination, it is very unlikely for the majority to believe that it is discriminating this minority. Thus you have dissent and the possibility of hordes of angry down voters "brigading" that channel. These brigades may even be organized or supported by country in question because it doesn't like the negative views the channel is conveying.
