Quite true; Digital Restrictions Management (contrary to what another poster said, smart people do realize and don't allow the reframing of the language away from how most people experience DRM) doesn't affect those who get their copies stripped of the restrictions as is commonplace amongst those who share. DRM chiefly adversely affects those who participate in the process (whether they spend their own money to do it or are given it gratis).
DRM is the excuse publishers use to justify the ongoing control over one's computer, spying regime modern-day DRM schemes make possible and use, and thus pose genuine risks to everyday computer users. This is not about "balancing" rights as another poster said, this is about copyright holders and their business partners using a mechanism to get more control over your devices, your privacy, and your life than they ought to have. To publishers who claim they wouldn't engage in the process without DRM, I say that's fine but I want to see proof and lots of it; please don't publish without DRM controls you couldn't have a few short years ago (remember that DRM schemes always become more onerous over time and publishers always try to convince the public they can't get by without the higher degree of control). Let your competition distribute their work at whatever price they think they can get DRM-free and do with the reduced competition. The publisher's threat is (taken on the whole) an empty threat and everyone knows it.
