you accidentally dunked a lot of communist parties out there, the brazillian communist party for example shun militants that make youtube channels and have kinda of a conservative view on leninism that printed paper is the only true way.

anedoticly i say that internet propaganda works, if you know how to surf the algorithm and bypass some limitations of private monopolies, i never met personally a communist or seen a printed paper in my life, i got into marxism via internet propagandists
