All kinds of people from all kinds of places read HN, so maybe better to use more general language - referring to “Chinese shipbuilding capacity is over 230 times greater than _ours_”
Unless a visitor is unaware that this is a US website, then it would actually help be more informative than otherwise.
And if a visitor is already aware, what difference does it make?
Not because this website happens to be operated by a US company, but because of US defaultism. If on the internet somebody forgets that other countries exist or that people from other nationalities might be involved, they are American. Occasionally somebody complains how non-inclusive it is, but for the most part we all ignore it
Is it not?
Why do we need to be careful not to offend the Chinese? Unless we are worried they are tracking HN accounts?
Or maybe you are saying, it should be more specific, and say "US" instead of "_ours_".
