I don’t know anything about the group you mentioned, but it seems “Koch Brothers” is high on the list of liberal agenda-pushers as a hot button of late. My liberal relatives commented on their liberal blog about how they will no longer buy Dixie cups since they found out they are made by “the evil Koch brothers”.
They pestered me for several months. They finally dropped me from their email list after I never donated and I would use their website and campaigns to email Senators and Congressmen to support offshore drilling and lease Fed lands to drill. In their name! I know Robert Redford is affiliated with this bunch of ecotards.
