There’s nothing ironic about it, much of cyberpunk is an exploration of the totalitarian nature of hypercorporatism.

It’s also not a variant of communism: first, in the Marxist-Leninist interpretation the purpose of the single party is expression of and progress towards the dictature of the proletariat, the single-party state is not communist (they claim socialism instead) and the ultimate goal is self-abolition (turns out all other issues aside it’s difficult to make such a system abolish itself).

Second, Libertarian Marxist as well as Trotskyists oppose the use of a transitional one-party state and “democratic centralism”.
