Your argument: lemmy is shit because its creators are communists and it isn't decentralized because most of the traffic is on lemmy.world

yes, Lemmy being created by tankies, genocide deniers and tech bros is the reason why most servers are rife with misogyny and incel mentality. that's why women don't feel comfortable participating and most active members are men. the fact that the gender hierarchy keeps reproducing itself all over the fediverse inherently disproves the myth that Lemmy is decentralized (as in abolishing hierarchical power). that doesn't mean that I don't appreciate this experiment for what it is and I definitely prefer the limited freedom of movement I enjoy here compared to the nonexistent freedom on Reddit.

BTC is and still is a decentralized project, a few actors gained a lot of power over the network but that is another story, similarly you could argue that a bunch of people run the finance world.

the US is and still is a federal institution. just because Trump became dictator that doesn't mean that the country is fundamentally flawed and states rights hasn't always been bullshit. just one more election will get our freedom back bro I promise! /s
