I don't know exactly what this means, as the implementation details are hazy, but if this entails substantial support to the ACLU (in terms of lawyers, money, or both), then that is awesome. I donated to the ACLU yesterday and I'm encouraging everyone I know to do the same.
While I don't object to many of these organizations, I take my privacy very seriously and I wasn't aware when I donated that my personal information would be given/sold out the way it has been.
