If Supercell is located in Finland, why can't they translate CoC into Finnish

Not everyone HAS to know English. Hay Day is their only game with a translation, but it's poorly translated, considering they are from Finland. What a disgrace. Rovio should do the same for their games. At least King translates their games into Finnish.

This is neglecting the almost extinct Finnish speakers, considering that Supercell is in Finland.

THEY EVEN HAVE THE FINNISH FLAG AS A DECORATION.

Why must this beautiful language die in favor of Britainization? (coming from an American with Finnish neighbors)
