How many native Chinese don’t have WeChat already? WeChat has 1.2B users. China has 1.4B people. I suspect the rest are too old or too young. Basically, it’s impossible to operate in a city without it.
The registration is cut off for now. The point I was making was that this probably doesn’t have much impact on the usage. If you didn’t have it before, you’re probably reliant on someone else with it and that’s just getting extended by a few weeks.
It's not like the world is static.
