Within that statement, you are trying two deliver two different, completely antithetical messages:
1. You are asserting that the Chinese government is not at fault and is benevolent and blameless and pure and innocent, because they didn't directly ask GOG to ban the game.
2. You are also
asserting that GOG had to ban the game to "ensure their interests"...which is a euphemism that means "GOG felt they needed to ban the game, because
they fear that if they did not, then they would make the Chinese government angry with them."
So...my point is, your second premise completely disproves your first one.
I don't see any contradiction here. The government is of course not benevolent, they just don't deal with small fish. And nobody in China would have even known about the game being released had it not been for the fact that GOG decided to tell everyone themselves. There's an earlier post by Mori_Yuki
that has a quote from GOG's announcement preserved:
That aside the real story can be found on Weibo ... Chinese gamers threatened to boycott CP2077 if Devotion was not removed before it was even added. They also threatened CP2077 because they found signs of promoting Taiwanese independence consciousness ... This is where things stand and this is what GoG had to say about hurting Chinese gamer's feelings when releasing Devotion on their official Weibo page: 「GOG.COM 保證不會做出傷害大家感情的事情，請大家放心」。Which roughly translates to GOG.COM promises not do anything that will hurt everyone's feelings. Please rest assured.
What likely happened after the announcement is that GOG faced a predictable backlash on social media as people were trying to one-up one another calling for boycott to demonstrate their patriotic virtues, or something to that effect. Of course the social media are tightly controlled so it'd be possible for censors to stop such messages from spreading but why would they, since (1) people need something to complain about, (2) they were not complaining about the government, (3) it might even be useful (one way to make sure the Party stays in power forever is to convince the people that everyone abroad is out there to get them). But it's not that the government started all this, they just didn't stop it. Maybe the censors helped a bit here and there by deleting a few dissenting voices to make sure everyone really was either on the same page or out of the picture but that's the likely extent of their involvement.
Then, CD Projekt/GOG just panicked and overreacted, taking the decision to delist the game worldwide. If you think about everything they have done so far to maximize Cyberpunk 2077 earnings, it's not really that surprising. They set an impossible deadline, released an incomplete game, told everyone it worked great on consoles, did not provide the console version for reviews, prohibited PC reviewers from showing their own footage, bribed influencers with cameos, etc. I don't want to trash Cyberpunk 2077 because it seems the game isn't really as bad as some portray it to be, and I'm sure it will get better. However, considering the amount of shenanigans surrounding its release, throwing GOG's reputation down the toilet to prevent any possible (however unlikely) boycott of the game in China would be par for the course and is just small potatoes in the grand scheme of things.
Of course the above is just speculation on my part but a scenario like this would explain how GOG could have banned the game to "ensure their interests," while the Chinese government would have been "innocent" with regard to this. And I think it's the most likely scenario. Everyone looking for excuses to put the blame elsewhere (there is even a post where someone blames Visa and MasterCard) is just making things easier for the most obvious culprit.
But the way china rules, with it's information warfare, even if it came from the people, it still came from the government. They're trained and encouraged to be the government's advocates, even in your scenario written above. They compete to virtue signal, which surely comes from a government policy.
