At least it is not on Google Play anymore:

and by

it is also not on Apple's app store anymore. What happened is "As Nguyen had promised, August 2014 saw a revised version of Flappy Bird, called Flappy Birds Family, released exclusively through the Amazon Appstore for the Amazon Fire TV platform."

You are right, it was not put back up by the original developer. I guess I just conflated it with the subsequent clones because by the time I heard of the game it had already been removed but then later I was able to play "the game" still.
