That’s a good point about taking. In an old-school socialist country like that, he might be hitting such a high tax band that he doesn’t have much of a financial incentive to keep it live after a certain point.
Or, maybe that’s the smarts here: he’s taking it down to set up shop in the U.S. for the next thing, which might well be Flappy Birds redux. This could be an Angry Birds-esque marketing explosion/nightmare, if one is into that sort of thing.
