Well we need an actual lawyer or judge here. Technically, Blizzard doesn't consciously choose what to distribute, its users do. And lets assume there's no proof the original author uploads the map to bnet, but its some random user instead. There's no staff at blizzard approving it what to publish on battle.net (yet), let alone a para-legal officer that knows the law, so I'm not sure what EU judge would say about this. If you distribute via github under some license (GPL or otherwise), and never use new bnet/wc3 (in a capacity a legal-discovery-action or judge can't prove), then I'm pretty sure that license takes precedence 100% of the time. How much money will you win? who knows. Blizzard can just comply and delete the maps instead, and pay some minor Fine to the EU/USA or whatever country fined them for breach. Chinese law is different. If you live in Asia, you can pretty much steal entire wc3 source code and no one would care (see Netease). I mean Activision-Blizzard can send ninjas to remove you I guess.
