I think you all need to take a chill pill.
Mr Rockwell lives on controversy - literally. This post, and others like it, provoke people to visit his site, and he gets more advertising revenue.
He likes to be controversial and extreme - it provokes debate, gets more hits.
The guy isn't stupid, and he doesn't pretend to be unbiased or accurate. His motivations are simple: generate traffic.
Once you realise that, comments like 'I never use a DSLR for anything now, I use a Leica M9' or some other daft thing become more understandable: he is all things to all men, and has an opinion on everything - even if its a stupid one.
Sending him letters is great, if it makes you happy. But don't expect him to change.
Cameras are just tools. Some are good for some things, some for others. There is no perfect camera, and there never will be - the laws of physics make that a certainty. Ken just plays that diversity to his advantage. You think this is any more ruthless than Apple, Google, Microsoft or Canon ? I think not.
