After reading /r/gamedev on Flappy Bird I got quite disgusted by their community. I hope doesn't represent the whole game development community. They seriously compared Flappy Bird to more in-depth games and took its success as some kind of threat without even realizing that short and addictive entertainment does sell. You can't compare Flappy Birds to "bigger" games, it just doesn't make sense. Flappy Birds is an amazing game in its own right.
It's embarrassing but in my experience many game developers are quick to denigrate Flappy Birds. I don't think it's restricted to /r/gamedev. We can speculate as to why game developers feel the need to rip games apart, but ultimately I think it's amazing that Dong created such a hit and a shame that he's felt overwhelmed by the community's response.
