When they hit this fundraising goal, he tweeted, "That's it. We did it. For US. For @aaronsw. Tears, and sleep, and endless thanks. #MayDayPAC" (https://twitter.com/lessig/status/485233905545400321).
"For @aaronsw." Lessig says in the documentary that it was a conversation with @aaronsw a few years back that convinced him to move on from issues of copyright and into "root issues" in politics, like campaign finance and corruption.
MayDay may not succeed, but it has already raised $5M and Lessig has a good track record for achieving change, so one must assume something positive will come out of it.
Though I identify with your anger, I think you can channel it positively.
As RFK said,
"Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring those ripples build a current which can sweep down the mightiest walls of oppression and resistance.”
