Considering that Ucool and Regan Mercantile's main headquarters and the servers which you play on are based in the US one could (on a not to far stretched imagination of idealism) say your asking to discriminate against them for celebrating a National Holiday in their own home based country.

Seriously though if your even going there, I find the complaint far to picky against a game that is Free to Play. All of Regan Mercantile's games are Free to Play, you on your own decision you can purchase with real money items to enhance your own gaming experience but nobody is forcing you one way or the other.
