No. If the device has it, the device would have to delete it. And China is a running a back already and opened a second group in wechat a couple of hours ago.
Chinese 🇨🇳 have learned that the CCP may stop the client from being downloaded, but users can still sideload the app and the CCP cannot stop the protocol.
I've heard of people using AltStore in modern times to sideload apps, but I don't know anything about it. I used to talk to my man Jay Freeman back in the day about Cydia and jailbreaking though.
China is using the andriod apk's, working on an apple sideload, and sharing the app they already downloaded 😜.
