Allowing other players to see your country isnt really a bad thing. It allow other players to help you catch impersonator, thus keeping your account/nick safer. The players had reported many impersonator by checking and comparing the impersonator's country and the real user's country. This could also help in preventing users from using VPN as other players can check it( VPN could effect others' gameplay due to latency ). I dont see the reason to hide your country.
