Valve and GoG aren't comparable to Spotify or Netflix because the former use a "buy model" and the later use a "rent model." Most of the point of the DRM for Spotify and Netflix is just so you don't sign up for a week and download the parts of the catalog you like and then quit. That's why spotify uses DRM and itunes doesn't.
