People there are so greedy, so eager to lick rich people’s balls, and so likely to throw insults and downvotes at you, if you give any hint that you support communism. It’s honestly such a disgusting place, full of slavers pretending to be smart, kind and moral.
Genzedong is another big communist sub purged by reddit. My guess is reddit will start to end when even “softer” leftist and anarchist subs start to get banned, such as r/latestagecapitalism and r/piracy. This coupled with overall enshitfication will lead to mass abandonment of the platform, which will allow for a place like lemmy to replace reddit in the consciousness of society. Things tend to get destroyed when capital and profit become the main justification for them to exist; but it may take some years for that destruction to happen.
Let us hope but also be aware that Lemmy.world is basically reddit and what many reddit users wander to when searching for an alternative.
