the bottom line is, LEGALLY speaking, you can implement all the DRM you like on whatever digital content you wish to put out there. All the community (such as the Slashdot crowd here) can do is give you opinions on how ethical or smart such a thing is.
IMO, you're rarely going to find someone trying to make a living doing "creative" things who doesn't like the idea of "locking them down" in some fashion. Sometimes, it's not even the creator, but the purchaser who enforces it! For example, I work for a firm that puts together marketing and creative ad campaigns, plans shows and expos, etc. Even though everything we produce is original material our team came up with and saw through to completion, we're not even allowed to display any of our work on our corporate web site! Our clients practically always demand we sign a contract with them preventing us from sharing what was done.
But as someone who has dabbled on both sides of the fence (as a musician trying to produce material, and currently as a typical content consumer), I'm convinced DRM is a universally bad idea.
The original article's statement that, "In my eyes, when people stop getting paid for what they do, they'll stop doing it." is a big part of the problem. A true artist creates because he or she feels a basic need to do so. Most of the time, whether one is a musician, a sculptor, a painter or an author -- profit is FAR from a sure thing in the beginning. These people produce a lot of material at what's usually a net LOSS for them. (Why do you think you almost always hear musicians tell stories of the crappy jobs they had to work to pay the bills while they performed their music at night, for years?) A good friend of mine is an aspiring author, but he works both a day job for the government and teaches kids Karate on the side for income. His books are his passion, not his income source.
Now, I fully understand and agree that these people are all essentially gambling / hoping that all their time spent on their art will pay off in the long haul .... that it's all part of how the system works that you'll produce and produce without much or any pay, until you get noticed. But my question then is why does that whole mentality sudden;y change when profits eventually come? Why is the same artist suddenly "entitled" to getting paid for every single copy of his/her work that gets passed around?
The truth is, I think we have too many people in the arts who are doing it for the wrong reasons! That's why so much modern music is mediocre, and why so many video games are just rehashes of the same formula. If you're motivated by "getting paid", you need to go work in a job where you earn a guaranteed paycheck for every hour of time you spend working, or an annual salary paid out in bi-weekly installments.
It's just opinion, but I truly believe that the only "right" way to pursue an art (such as music) is to do it out of the pure need to create the best work you can possibly create, and share it with others who get enjoyment from it. If you're good enough at that, people start taking an interest in compensating you financially for it. Great... but don't let that change anything for you. Don't stop to "count your money" or you'll become a lesser quality artist for it.
