Satoshi has a Japanese name, not a Chinese name. I thought the Chinese hated the Japanese. Why would they give him a Japanese name if they secretly invented Bitcoin using him as a front? I don't know what the Chinese equivalent of the CIA is called but I don't believe they invented Bitcoin, or that the US CIA invented Bitcoin.
Misdirection. If Satoshi was a bunch of sinister Chinese folks then you may as well choose a name from a country you're not hugely fond of and use a style of English from a place far, far away. We'll likely never know anyway so there's no point in getting our knickers in a twist.
