Something important to note about China's private sector compared to Western liberal ones, is that it's highly regulated, and because of that a lot of the disgustingly abusive ways that private corporations treat the public just doesn't happen there.
For example, with ads in apps. It's just accepted knowledge that with 'free' apps, you are the product and the app sells your data and/or attention to advertisers. In China that's all extremely regulated: if you see an ad, it's got to come with some kind of special offer or deal that benefits you, and not in bullshit "mark the price up and then discount it back down" kinds of ways.
So in the West the app sells your attention to the advertisers; in China the app sells access to you and the advertisers give you coupons and discounts (that automatically get processed by the app's payment system) in exchange for your attention.
And the most important part is that if people report an ad, the government will be on the side of the public when it investigates, as opposed to the toothless reporting systems that nobody bothers with in the West.
The net effect of this, and many many other kinds of 'authoritarian' regulatory laws that don't exist in the west, is that I'm not experiencing the same kind of enshittification in China as I am in the West.
