It's quite common for Asian people of the family name:given name system to westernise their name to more easily navigate the cross-cultural interactions. To me, it's a pretty big step. I doubt many westerners do it the other way.
It also means people are less likely to take the piss out of them, and given some of your comments in the past, I'd guess you're one of those people.
It should be pretty obvious why a french man hasn't done this.
