Sometimes companies are chill about non-core stuff having their name on it and will let an individual who created a cute game during a hackathon show it off. "Is this video streaming related? No? Okay, just make sure it's not offensive and there's no way anyone could take it too seriously."
Dong Nguyen, the creater of Flappy Bird thinks different about this topic - this is also the reason why he took the game down for the app stores:
'"Flappy Bird was designed to play in a few minutes when you are relaxed," the developer said "But it happened to become an addictive product. I think it has become a problem. To solve that problem, it’s best to take down Flappy Bird. It’s gone forever."'

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."
