I can see where the guy is coming from. Even extraordinarily minor celebrity - being known by a few thousand people, which I have experience with - can get creepy, and that's when it's expected and intended. But something like he's had happen, if it wasn't actually a goal? That could easily get brutal.
I think that people still tend to think that success and resources are simultaneous, but the latter can often perilously lag the former; being in the position of a lone guy who's suddenly expected to have PR, media savvy, and the development quality of the organizations that are normally making multi-million user games has got to be nerve wracking. And I'm willing to bet that a lot of people (say, those who are criticizing the game for being derivative) are judging his product as if it was made with resources and intentions that he never had.
On the bright side for fans, I've already noticed a gaggle of low-rent knock-offs slithering out of the woodwork; no doubt we'll soon be awash in "flappy candy bird story saga" clones to which we can unwittingly deliver our personal data to our hearts' content.
