Earlier quoted context omitted.
Given that one in five person on the planet speaks Chinese as their first language, lack of “foreign” contribution will probably work out okay for them. Global contribution is nice but certainly not necessary. Whoever started the communities have the right to set the rules, using Chinese for (primary) documentation and discussion being one of them. If you don’t like it you can start your own.
Pure numbers mean nothing. Neither a farmer with no internet nor an urban Chinese citizen with a mobile internet but no actual computer is liable to contribute much. There are 800 million Chinese internet users almost all are mobile only. Those that work as professional developers are expected to work insane hours that are unlikely to leave much time for public works after 9 to 9 6 days a week.
What's that supposed to imply? Just Googled "number of software developers in China" and "number of software developers in the world". Got 5.79 mil (2017) and 23 mil (2018) as answers. Not sure how accurate but can't be that far off.

I didn't pay too much attention to that story, but having talked to a few software developer friends in China myself, I'm inclined to say it may be a widespread problem but probably not universal. Whether that's true or not, I certainly see a fair share of popular open source projects coming from China these days, not one in five of course, but given their relative isolation and my inherent U.S./Western bias the number that caught my eyes are still quite impressive.
Not to mention there are a lot of corporate open source in China as well. In fact, just like in the U.S., a good chunk of high profile open source projects are corporate-developed or corporate-backed.
Moreover, whether one in five is accurate wasn't even the point of my post.
