Over at N4G.com , user manimal posted a short but to the point comment:
DRM= not free at all.
As a linux hippy, I am so anti DRM. I want to do what I want to my content, when I want. Create backups, use on any machine that I own and what not.
However, when DRM is done right, it is not an issue.
With steam, I have yet to hit any barrier. As I am mainly a MMO player, I am very comfortable with linking a game with an account. In a way, Steam improves the MMO experience, managing the patching offline. As well, I can backup the files and Steam allows me to play the games on any PC.
Publishers will insist on DRM, as they are the only one who benefits. While piracy is a real or perceived threat to their profits DRM will not disappear. It is up to us to prove it is not, or at lease show the benefits outweighs the negatives. It has happen with music, not so much with movies, books and software.
