Here is how I look at it. Yes, it is against the law to download things you did not pay for. But if no one protests against the companies that are not willing to innovate, and are so large that they stifle other companies ability to innovate in this arena, then we will never progress to better ways of consuming content. Example was already used in this thread, but before Spotify was viable and could innovate in the music space, Napster had to be around to show the music execs that people were not satisfied with the status quo.
Similarly with TBP and torrents for movies - movie execs don't get it. I can get a better quality experience downloading a TV show or movie from a torrent over watching it in some of the "acceptable" formats that are currently provided. At some point, a company will be born that will deliver movies/TV in a better way (maybe it's Netflix) and people will be willing to pay AND tv/movie execs will be willing to license their material to them because they have been shown that their current model is not viable anymore.
There is so much room for technical innovation in the delivery of commercial video (tv/movies/etc) to people these days, and the companies are worried about it cutting into their profit margin because they are not in a position to take advantage of it. So they take to trying to force technology to slow down, stop advancing and stop innovating by way of the courts, their bully power as monopolies and we should all be upset with them for that.
My message to the large corporations - make it easy and convenient for me to watch your video in the fashion, manner and timing that I want to watch it in, at a fair price, and I'll happily pay that price. They are not there yet. (FYI, although I believe this, I don't actually torrent very often, I generally try to stick to the legal methods of watching video when possible and pay for Cable/Netflix/etc as well.)
