The ransomware doesn't do what I as owner of the computer want and nothing which serves me a purpose. The comparison doesn't work. If you look for a comparison: DRM is like a book publisher printing books on special paper which prevents copying and which can only be read in a specific angle so I can't easily take notes containing quotes from the book. All to protect those rights. (Edit: actually that example is missing a piece - you need special reading glasses to be able to read it, that's what DRM is doing on my machine) And yes - Napster was an issue for the music industry. Suddenly their content was there for free and easily accessible. But then there was Apple, giving music away DRM-free with even better usability and for an acceptable fee.
