Except in practice it’s not proletarians doing these things, it’s bureaucrats who end up forming their own class and class interests in the name of the proletariat. The average proletariat isn’t actually the one who makes these rules or checks or applies censorships. See China, USSR, Cuba.

There shouldn’t be classes to begin with. Eliminating hierarchies in lieu of anarchism deals with the issue without it being “another dictatorship”
