What you called "clear worker rights violations," was just the fact that unions are required to be a part of the All-China Federation of Trade Unions, and aren't allowed to be independent from that federation. This isn't a violation of worker rights, though, as the only purpose rogue unions would serve is undermining the socialist system, and would be vulnerable to foreign backing (such as from the US Empire).
The socialist state is already run by the working classes, I recommend Roland Boer's Socialism in Power: On the Theory and History of Socialist Governance to get a better idea of how and why socialist countries hold the structures they do. Roland Boer also has a good book called Socialism with Chinese Characteristics: A Guide for Foreigners, which is more specifically about the PRC and goes beyond the structures of governance to the more broad system of socialism in China.
Regarding your participation in MeanwhileOnGrad, you should know that EmoPunker cut off the final replies, where they called defenders of Pol Pot "genuine socialists." These are the kinds of posts on that comm, they selectively remove context that makes themselves look worse, deliberately misframe reasonable comments, and the comm itself is run by a zionist. This kind of anti-communist bar is a gathering spot for genuine fascists, but it seems you're fine with participating there.
