Lemmy was founded by a Communist, and Communism in theory is focused on creating a Stateless, Classless, Moneyless society via Worker ownership of the means of production. It's fairly easy to see why Lemmy, a platform built on decentralization and a rejection of the profit motive, appeals to leftists like Communists.

Additionally, most Communists practice Materialism, and analyze historical events and structures on the basis of their material conditions. Rather than believing tools have mystical properties that corrupt the minds of those that collectively own them, they look at why historical examples of Socialism have turned out the way they did, and seek to learn from them.

Nobody in any serious number seriously wants a dictatorship with an absolute state.
