Today is about taking time out of your usual routine to speak out in favor of a DRM-free society. We do not have to accept a future where our interactions with computers and published works are monitored and controlled by corporations or governments.
Here's my suggestion for an action item: free yourself completely from iTunes. I can't even begin to tell you how much easier it is dealing with all my media since I got completely off of iTunes over a year ago.
Refuse to continue to buy DRMed media and it'll go away. eMusic, the Ubuntu One Music Store, and Amazon's MP3 store are all great places to get the music you want without putting up with DRM.
