As a Chinese, here’s the background imo: Unfortunately, many people in China just forget what browsers and websites are. We use WeChat mini programs (and Electron apps) everywhere. Even if we’re asked to open the browser, almost everyone only have browsers like Huaiwei Browsers, Xiaomi Browser, 360 Browser etc., which have old Chromium/WebKit inside. People don’t recognise Chrome, Edge or Firefox 
This is also one of the disasters that multinational apps (that have some Chinese customers) often overlook.
I believe this is one of the reasons why Discourse is not known in China.
