The comments make it seem like it's more a case of users tolerating it due to the apps usefulness. Interesting video though, haven't had any contact with Chinese apps, so that was enlightening.

I agree that numbers alone might not mean much, but I do think B2C apps with millions of users have a higher bar in terms of design and polish compared to B2B/ERP apps.

Also, fixed typo!

I think the point OP is making is that the relative pleasantry of the experience isn't as important for end users as it is for us developers. My anecdotal experience bears that out: I shudder when I see a web-heavy native app, my non-tech friends don't bat an eyelid. People learn UIs, no matter how janky, very quickly if the end goal is important to them.
