Pressuring is one thing, but spamming and pressuring? Overkill, man. No wonder he decided to quit. He's trying to teach us a important lesson: Don't mess with legendary people, especially the one's who not only have literally tens of thousands of fans, but who make the movies you want.
And here's a message to all of you who spam and/or insult him: SHUT. THE. FUCK. UP. You already did the worst you can possibly do to a series. Those sprites were not stolen; there's a giantic, dark, bold line between stealing sprites and using sprites. It's only stealing if you claim it's yours if it isn't. And just because you use sprites and tween them and make movie clips with them, doesn't mean that it automaticly is crap. It's all in how you put it together and how complex it is. You're just jealous that you can't do it like he can.
There, the message that needs to be heard.
