Did marx at one point write about "take over and make mockeries of entertainment"?
It's becoming such a common thing it's on par with "attack cops" in the commie play book. What's the ideological driver of taking over and destroying entertainment franchises?
Destabilization of Culture is the phenomenon you're talking about.
The ideologue you're looking for isn't Marx. It's the Marxists who looked at the industrial societies resisting the revolution that came to Russia and China and asked: why hasn't this worked in the West? They railed against "Stabilization." They were upset at the prosperity which made the proles happy with the capitalist system. These neo-Marxists chose to erode the culture itself because they couldn't oppose the material wealth; they did this by focusing on intrinsic differences. They aimed to create a new class of "oppression" to create sett of proles who could never be happy once they were taught that they were oppressed.
Then they conducted a long march through academia to ensure that they'd be the teachers. They seized the means of cultural reproduction, instead of the factories. The creative arts followed, resulting in the destruction & subversion of modern media.
Welcome to our intersectional future: miserable people subverting and ruining our culture because of the way they were born.
Russia and China skipped democracy. They were still in feudalism when they had their first big industrial-capable political-revolution. Countries with democracy were able to peacefully adapt to the rapidly changing economic landscape. Largely by pivoting away from both capitalism and communism and towards socialism. Germany went too far towards socialism and wrested control from the elites so this pissed them off. But it is the future. It is inevitable.
