Probably because the justification goes as far as "I'm doing something some random megacorp doesn't want me to do" - and the average person could care less what a bunch of faceless millionaires (most of the time) think about what they do. Let's just throw the legalistic argument out in advance. It holds as much weight in people's minds as the speed limit does. Availability is part of it yes. Another part of it is respect, and the media industry has a systemic problem with showing any to its paying customers. Those in charge have yet to realize that all the DRM, all these systems serve to inconvenience people who want to give them money in the first place - and I think the idea that people can be chided into giving due deference to the whims of huge corporations when said corporations won't even do something as simple as sell usable product, is just a bit backwards. Yet another part of it is practicality, and XKCD says it better than I can: https://xkcd.com/488/ https://xkcd.com/488/
