Re: what is going on?????
OK. Say that some kid in a bedroom fiddles with open source firmware for your M9, which makes the shutter trip in a non-standard way, or means that the sensor runs hotter than specified, or whatever.
You run that Open-Source firmware and your camera breaks, costing you, let's say, $2,000 to put right.
Are you going to go after said kid in the bedroom? Or Leica? Or no-one, putting it down to experience?
