It turns out, you can make whatever statement you want. Perhaps you want to abstain because you think the quality or music being produced lately is sub-par. Perhaps you want to send a message to the major labels that they should stop suing their customers. It could be that by not listening today, you will appreciate it more tomorrow. Maybe you want to make a statement that if consumers keep stealing music, artists will stop making it. Whatever you want. Make a statement for why you are supporting it or not.
Personally, while I'd like to make some noble statement about how I'm not going to listen today until the major labels get their shit together (in general) - honestly I'm ultimately *not* going to support it because I don't think I can go all day without it. You wouldn't ask a schizophrenic to abstain from taking their anti-psychotic drugs for a day to make a point would you?! :-)
