That doesn't seem unreasonable to me. Do Anthropic et al have a "Chinese" button on their website and translations for all of their articles?

If that's reasonable or not really depends on what people they want to offer services to, no? No one* outside of china speaks Ehinese, while plenty of people, like me, outside of USA, UK, NZ, AU, etc. speak English.

*yes, there are for sure some people who speak mandarin, it's just not as widespread as English (or maybe Spanish)

Sure, Chinese has 1.2 billion speakers, and English 1.5.

Seems to me that an incompletely translated site is more serious than no translation.
