Dear Alison,
no one, literally no one, believes Nintendo of America's stated reason for firing you, especially not even the pricks who celebrate the firing.
I am ashamed of what some parts of game culture have done to you these last months, and I am especially ashamed that some of these despicable people think they're part of the DeviantArt community of artists.
Please don't stop loving games, please don't stop participating in DeviantArt, and please keep a stiff upper lip.
I promise that I will, much more than yesterday, criticise the dissemination of vicious, factually incorrect slander wherever I see it. And if there's anything people can do to help you personally, please do ask for that help.
Best wishes,
Needleblade
