I kind of disagree with the article. Let's say I make a game, an IAP based one, and then I release its source code together with the game. The 1000 talented and hard working employees company in a country like India picks up the code legally as FLOSS, recreates a new content for the game and releases their own version. New brand, new everything, but the same game. You can't sue them for this, Zynga wasn't sued when they did pretty much the same, but they have to do their code too. From that moment on they can make things 1000 times faster than you and you are broken.
Of course they can do what Zynga did and imitate my game but that would at least give me a head start on the market.
