They have a trademark in the EU and US according to the reddit thread. The problem is their app was removed internationally instead of just in China, and they are having trouble appealing it.
I wonder if the original game developer was in watch mode while all these trademarks over EU, US and China was granted.
@mastazi, If you have trademarks over EU, US - why not start a petition and let community help you bring down Apple to reinstate you?
