It wouldn't surprise me if they were just dishonest populists who change their opinions to whatever people want them to, and don't care the slightest about what is going on.
The only way it'll catch attention is if we assume it will, and follow it, and spread it. I don't have a problem following it, since I don't watch/buy/pirate movies or music. I do subscribe to a science magazine, I'm not sure if that counts as "buying" in this case... I guess it does. Then there are the games, which I do buy sometimes, but I wouldn't have a problem waiting a month.
I don't think it would be that hard to make a "Black March" personally, but maybe it's different for other people?
Also, since it'll show up on their reports for three months, we could start now to double our effects.
