Well, this is kind of a delicate thing. I don't actively mistrust what others have said, particularly those on this site that have their fans. My deal is that while you obviously trust them, I just don't know them enough to know if they're reliable or not. I can name a guy that I used to trust totally in his information about the inner workings of Disney. But he became so rabid in his disdain for the company that he lost all credibility. Many people worship Jim Hill. I find that his constant hyperbole and his use of his own colloquialisms in emails supposedly from others have combined to bring my opinion of his writing way down.
In this specific situation, many have said that the yeti fix is a relatively simple one, and Disney just doesn't want to spend the money. That may be correct, but it doesn't feel right to me. They're getting such a bad rap over this that if it were indeed as easy as some folks say, then it'd would have been done years ago. It makes more logical sense to me that the fix would require shutting down the ride for months while they spend buckets of money to do the fix.
But again, we're talking about the same company that has left the People Mover track up in DL and rotting away for years now, so who can say? All I want to say is that I mean no disrespect for others who express differing opinions here. They may indeed be right.
