I have zero issues with sites coming and going, or new sites coming online and beating old sites. That's not the issue with Panda. With Panda a site doesn't move down a position when a better site takes its place. With Panda, HIGH QUALITY SITES are completely devalued by an artificial intelligence experiment gone bad. There's a huge difference between saying everything needs to stay as it is (which I'm definitely not saying) and that Panda is good or responsible.
