The whole thing is disappointing all around. It was clear just from the outset that the TiaG application was intended for piracy, there's absolutely no reason for it to be included. For the reasons stated (Cydia is not in Chinese) they could have just offered patches with new translations. If people found the relationship between TiaG and kuaiyong (another piracy store) in a matter of minutes, I'm not sure why the evad3rs didn't.
Now ultimately their jailbreak is being used for piracy by a company who paid not a dime for the exploit kit. I'd have been happier to see them take the money and donate the lump sum to EFF for similar.
