Aspiration for the masses and policy reality are different things. They will say monopolies are bad, but what they mean is only if the state doesn't control them. The CCP has huge state run monopolies and there's nothing you can do about it. You can't understand their policy without understanding Marxism-Leninism. When pesky reality gets in the way of policy, it's called corruption.
In communist or post-communist countries like China and Russia, the percentage of government workers is extreme. To them, all social action is political action, and that includes economic. Since there is only one party allowed, any economic action (and thus political action) which threatens the CCP is unacceptable. They leave other private companies alone.
The CCP is bad and this conclusion is justified not only in theory as a distant observation of ideological concepts, but from their behaviors around the world which echo some of the causes of World War 2. That doesn't mean Chinese AI companies are bad, but the CCP will certainly find ways of using it for its purposes. For now, they're quite far behind on AI, but they deserve credit for optimizing for some use cases which masks poorer generalization.
