Sure. In short - by the 70's, soviet intelligentsia (that is artists, media people, scientists, etc) have perhaps not gotten anti-soviet, but started expressing it. Look no further than the ultra popular (at the time at least) Eldar Ryazanov. It started slowly. A lot was legitimate criticism - bureaucracy for example. But it built up and built up, until they started out churning outright anti-communist movies, like "Dog's heart", which made an absolute mockery of the October revolution, of the people who made it happen and of the subsequent rebuilding.
Now, so what, you might ask. It's just some pissy actors being pissy, happens everywhere. Problem is, basis and superstructure are interlinked, one informs the other. And the superstructure for socialist way was giving way to anti-communist one, just as the market reforms were speeding up.
Many times liberals and their media/social media within the PRC flare up each time a democrat is elected in the US as they are given funding to spout and spread their bullshit (a term we usually refer to as 'dog food').
To be honest the environment was much worse a decade or more ago. Imagine being denounced as a pinko by Chinese liberals inside the PRC in the 2010s and prior just for saying a single positive thing about their own country lol.
Talked to a few of them recently and hearing their fear of the next generation being so "deeply red" was interesting, because they were hoping that everyone would become even more liberal and end up like Japan, full of pretty anime and pop culture while being subservient to the West.
Nah, this is just some spoiled brat. IME, the closer they are to having a peasant background, the more they put their trust in Xi and the CPC. It also helps that Chinese tourists can see the dilapidated shithole that is US infrastructure with their own eyes. Plus, China is at the forefront of technology at this point. Their consumer products are beating the US. In Blackshirts and Reds, Parenti mentioned how those Westophile liberals were suckered in by cheap high-quality consumer goods from the West. In the 60s, this was true, but now? Chinese liberals can buy cheap shit made in China and shipped to the US or they can buy high quality products made in China for the Chinese domestic population. At a certain point, it's just pure ideology. Even those loser HK protestors have conceded that the Mainland has better infrastructure and living standards by malding "uh aktually, since Hong Kong no longer has freedomTM or democracyTM, we might as well go to the Mainland where the trains are newer" lmao
