Ironically, Rick Lyon is also rumored to have been fired from Sesame Street for being a bit of a loose canon and comes off similarly bitter. So there's that.
Here is a question though? Why the blind support for Steve?
Even with what we are reading, why not admit that we might know the guy beneath the puppet like we think we do. He wasn't Kermit. He's just a guy. Meanwhile, we completely discount or are angered at what Disney or the Henson's are trying to get across. Someone said that they would prefer that the Henson's simply call it creative differences and leave it at that. How can they do that or just sit back while Steve has started a blog, is doing interviews, etc. where he is creating a narrative that fails to tell the whole story?
As fans, maybe it's just hard to admit that the guy we look up to isn't perfect and may not be what we expect. He literally kept the character from showing up when he was supposed to. He may have put down his coworkers and kept some from performing at all. Even if well intentioned, he may not have gone about it with tact.
Also, enough with the "I can't imagine anybody but Steve as Kermit." outrage already. Do you realize how ridiculous that might sound to those of us who were alive in the 70's and 80's and earlier? You'll adjust. In fact, the characters depend on it.
