Much like every other nation on Earth, the government will seek to take a hand in the largest businesses operating in their jurisdiction.
"Expecting" the Chinese government to control every business in China is very dystopian and baseless. They couldn't do it even if they wanted. The same way my country can't regulate a simple scooter ride-sharing startup during a pandemic...
I wouldn't question China's control over companies like Alibaba. I wouldn't question the US' control over companies like Google. Which again is a totally different ballpark.
This is at the very least much more explicit than the control political parties in the US exert over businesses.
But yeah. I'm only here to say that equating control of giants to be very different to control of everyone.
About ten years ago there was the infamous "3Q war" where Tencent and Qihoo engaged in pretty ridiculous measures over the messenger market by blocking each others usage on consumer machines when the other one was installed, orchestrating fake media articles about pornography, police raids and at some point calling on users to go into a general strike. The war basically only ended because at some point the government stepped in and for the first time enforced anti-trust law.
This has changed to some degree but China's tech sector always was so hilariously under-regulated it makes most Western countries look socialist in comparison
