There was a conversation with some western dev how they kept saying Chinese devs don’t work with scale like Meta/Google do, so they don’t have experience in it either. That was also an interesting thread to read, because without thinking about anything else, WeChat itself has more than 1B users. I’m not sure if it’s pure ignorance, or just people want to feel better about themselves.
I agree that a good chunk of Chinese apps’ UX is trash though.
