That's because all the top companies in any sector in China are subsidized and heavily supported by the government. The distribution isn't as organic, it's more a matter of in China, crossing the threshold to being the "golden child" and being guaranteed success right after.
I don't know enough to support their extreme position, but for the sake of information:
Part of it is state-owned banks (the dominant form of banking in China) offering attractive lending to state-owned enterprises, as loan officers avoid the risk of being accused of corruption.
Also, there likely is/was more direct encouragement of exporters (e.g. by subsidies), similar to other countries, but my source doesn't specify if this currently applies to China.

None of the top Chinese tech companies are state-owned. Also 2010 was before Xi Jinping. Things have changed a lot now. Now they get striked left and right by regulations. Just look at their stock price.
I'm not sure where you guys are coming from, but the top officials of China acknowledges this is an issue. Are you saying that they are wrong and that China doesn't have a huge problem with corrupt officials? Or why else are you questioning these things?
In fairness accusations of corruption to remove political opponents or "troublemakers" have a long and storied history of application by genocidal dictatorships like China, democracies, and basically every form of government.
So merely having an accusation doesn't really say much.
From what I know about how things work, the argument makes sense. Just denying won't cut it. You need to propose an alternative view. I am willing to listen.
