Everyone but the state, and unfortunately the capitalist states have much more power to push their narrative. Thus "communism" became the enemy to latch onto, and now it's synonymous with Stalinism in the eyes of many.
Same thing happened with "anarchy" and it being synonymous with "chaos" in the eyes of many. But indeed, anarchy is order.
Edit: A quote from the linked article, absolute nonsense lmao.
On the Right stand the committed anti-totalitarians
Can you have communism without authoritarianism though?
well, we'd have a more settled answer if historically communists of all stripes weren't immediately persecuted wherever they win power (whether democratically or through revolution), but Revolutionary Catalonia strongly suggests the answer is yes. its most anarchist regions successfully managed themselves pretty well for more than 2 years during a vicious civil war before being crushed, and those are the literal worst circumstances possible to try and build an egalitarian, stateless, classless society in. i would imagine doing this is substantially easier without a well-armed state trying to murder you.
(also ironically, the anarchists in Catalonia sometimes had to fight the Marxist-Leninists who were ostensibly united with them against the Francoists, because the two sides had such radically different visions of society)
Well, authoritarianism isn’t the enemy of the authorities. It usually works out quite well for them, at least for a while. It’s definitely detrimental to society as a whole though, where communism is generally neutral (though more easily abused than capitalism).
That’s because it’s demonstrably worse than capitalist autocracy. Communism itself isn’t a problem, but it has yet to function properly at a state level; China came the closest, but that was still based on stratification and a ruling elite. And now it has the worst of capitalism as well.
