A few comments after looking over the posts:
I expected this to be a controversial topic (both my particular situation and file sharing in general), and I’m not really sure what I think of it myself; that is, I don’t think I have a “magic bullet” argument that proves the ethics/unethics of these activities. I imagine I’m not alone in my uncertainty; a lot of file sharers will likely admit, when pressed, that there might be something unethical about their behavior.
But the thing that shocked me most was that several posters reacted as though my “cheap” philosophy was unacceptable, presumably even if copyright violation were not a part of it. I don’t quite understand this line of thinking. I mean, I’m not being so cheap that I make myself miserable, and I’m not going around shoplifting things. I find that I don’t really WANT all that much stuff, and many of the things I do want can be had for free or for low prices, if I look in the right places.
Music is one exception to that; it’s something I do kind of like, but it’s tough to get it free/cheap in a format that’s not obsolete, and it’s not “essential” enough to get me to break down and pay full price for it. That’s why I brought up this tough question. But in general, I am cheap because I enjoy it; there is a kind of satisfaction that comes from finding your stereo speakers in the trash, or building a computer from eBay parts rather than paying Dell price for a whole (and probably inferior) system, or obsessively maintaining a 1986 car in order to make it run forever. You learn a lot by living this way, rather than just throwing money at every problem.
