I think the main reasons why he's taking it down is because it's "ruining his simple life" and because people are "overusing it".
If he's seriously doing it because it's ruining his happiness, and he's making anywhere NEAR that $50k/day number, then much respect to him for putting quality of life over dollars in the bank.
I could probably tune out the 13-year-old haters for $1.4m/month :D
So he don't want his $50k/daily anymore...
Well, if the game is taken off the store, this doesn't uninstall it from people's devices, would he still be making ad revenue from the already installed games?
The guy is living in Vietnam. He just doesn't want to be considered a high value target.
I guess I'm not up to speed on this Flappy Bird thing. But why is he doing this?
Maybe It's a seanky plain for invesment?
I don't think it's a plan for anything.
He seems like a really chill, simple guy, he just wants to make games. And being in that position, he must get a huuuuge amount of hate mail per day. Not everybody can deal with the majority of the internet being pissed off with you.
