The real problem is that YT also influences those social mores. It's a snowballing effect that no one is able to stop. New social trend >> YT starts to promote it >> Becomes social norm >> YT starts to enforce it >> New social trends are able to spawn only from the previous trend.
You might want to keep up this situation as long as it fits your point of view, but you have to take into account that this process will warp this exact point of view in ways that you do not control.
20 years ago the left was synonymous with freedom of choice and individualism, now there are hardly any traces of those values left. Excuse the pun.
If YT always bends to the "popular opinion", then it actually means that it has knee-jerk reactions to the most emotional outbursts. What influences the norm is in reality the base instinct, dopamine fueled, thoughtless reactivity without any plan or purpose.
It does not matter if you will take left or right wing ideology. Platforms like YT are instrumental in making sure that in the end we will get the worst version of it.
How the hell did the left end up in a poistion where they represent the worst mixture of Orwell and Huxley? I have no doubt that it would be near impossible to end at this place without corps capitalising on social moods.
