This is the Hacker News bubble in action. Most of the world, most of America, most of China, India, etc. haven't even heard of it. They ignore it and they thrive. Maybe you need to pay attention if you're dealing with certain European governments these days - I'm not sure because I completely ignore it and haven't paid attention since there was just OpenOffice and LibreOffice didn't even exist yet.
Open document formats have been the UK standard for things like .gov.uk for many years. About a decade IIRC. Ignored by some people (notably the Office of National Statistics, of whatever its called these days).

I have come across quite a few non-tech people who use Libre Office.
It has great (some people say better than MS Word with itself between version) compatibility with MS office formats.

So if China has heard of LibreOffice, they clearly didn't like what they've heard...
Moreover, what you write is monitored, and you may loose documents based on what you write [1].

So just like MS Word then
