Richard Esguerra from the EFF:
Apple’s announcement comes nearly a year after Amazon.com’s DRM-free MP3 deals went live, demonstrating that the record labels were holding the DRM card until they could wring business concessions from Apple (in the form of variable pricing). This just underscores that DRM is not really about stopping piracy, but rather about leverage over authorized distributors.
DRM-free music is certainly phenomenal news, but Apple has a long way to go before they can brag about being DRM-free entirely.
