It definitely looks like someone extracted the text files from the English early press release... In that case I assume not all text will be translated, or that there will be oddities in the translation. That said I don't really see how that's illegal... Translating a game is not a copyright infrigement AFAIK. The 'hacked' files are made by BIS and are intended to be used with an official BIS product and it's not like they make it easier (or possible) to make illegal copies of the game.
