Wechat hasn't really been super popular since AIM days. ~15 years ago when I was in China I don't think it even existed, and 10 years ago there was significant numbers of people using qq still instead of WeChat (or rather not in addition to? Lot of people still use both).

I don't think it overtook qq until like 8 yrs ago? At which point AIM was already discontinued, and 10 years past any kind of popularity.
