I'm very well aware of that.
Whenever I've been on the receiving end of a name change like that, I (and everyone I knew) found it obnoxious.
However, cultures differ. Turkey has a long history with name changes, and has been rather aggressive about them. When it became "Turkey," the post office wouldn't deliver mail unless the new name was used. Likewise, the capital has gone through two names since "Byzantium."
I was genuinely curious about local reaction. I have no idea, from the other end of the world, whether this was imposed by Erdogan as a crazy policy to everyone's annoyance, or whether it is wildly popular. I assume somewhere in between.
