"In the criminal law, theft (also known as stealing) is the illegal taking of another person's property without that person's freely-given consent."
For example if I make a copy of my friends coffee cup (which he purchased) and use that copy to drink coffee, would I then be stealing from the original makers of the coffee cup according to the definition above? I think not.
I agree with this, but alas the law does not. Currently, copyrighted software has the legal status of property. Most copyright holders believe what you describe is stealing b/c they want a cut for *every single copy* of their work, no matter how that copy is produced and distributed.
This
essay, first published in Wired over 10 years ago, is still a very useful read for anyone seriously interested in whether or not copyright is wrong.
p.s. I've paid for GC1, GC2, and Dark Avatar. I reject (c) but believe in supporting the arts and sciences. Plus the fact that you have to register to get updates is a pretty good hook, especially when the updates are as valuable as Stardock's tend to be.
