What’s particularly fascinating is how there is an almost complete absence of a leftist equivalent on YT. There are some leftist channels here and there, but you’re not going to get bombarded with communist ads after watching one video like you might on the right.
I like to tell myself that's because real lefties adhere to the doctrine of Gil Scott Heron, The Revolution Will Not be Televised, even though they won't understand 99% of the cultural references
In my country we still have a old school communist party, and despite their radical ideas like saying north Korea is a democracy or support maduro in Venezuela, when you hear their political campaign is all about raising minimum wage and a restricted House market. In the other way, when we look at the far right party, it's all about how the immigrants are eating tax money or defending a small government with a total control for one leader.
So it's not that radical left doesn't exist, it's just that they drop their guns and what's left it's not that loud.
It's strictly a function of funding and the economic power of the interested parties. Rich capitalists are, naturally, invested in promoting policies, ideologies, and politicians that will 1) keep them being rich capitalists and 2) make them richer capitalists. I don't know, but am fairly confident in stating, that there are not rich communists waging a communistic propaganda campaign in order to keep them being rich communists and making them richer communists. Certainly not in the Anglosphere, anyway.
You’re not wrong, but leftists also tend to spend an inordinate amount of energy and resources fighting internecine battles rather than trying to convert others. This does make it rather hard to do things like run self-reinforcing YT campaigns, assuming YT would tolerate them.
