Not surprising at all, they were just more serious in this battle. That's one of their efforts to fight and limit the financial system that is not their version.
In a country like China, it is not surprising that such restrictions are imposed through centralized applications backed by the state itself. But the question that arises is how the state can track the profiles that support crypto if they are not able to publish publicly, and this is what most of us exclude.
I mean, if I publish an article talking about cryptocurrencies, does this mean that I support it? And is there a possibility that the state is spying on the private conversations of users of the application? Everything is possible with a strict dictatorial regime like the one in China.
While Chinese people are only allowed to use Chinese-made social media apps, such filtering seems easier because app developers are within the reach and control of the government. And as is well known, China has abundant human resources capable of competing with anything new by duplicating into their versions, including applications and electronic devices. That is nothing but, so that the government can fully control it.
