I have to admit, I'd love to be able to modify the software in my microwave to disable the incessant reminder beep. But I'm not sure I agree in general that it companies shouldn't be able to copyright their own software, or put measures in place that make it impractical or impossible for me to modify it. Presumably I'm aware of that when I buy it, and I have options. But I think that's different from being able to repair it.
