Yeah, Credo is sort of a bizarre little company. They created a Super PAC to oppose tea party candidates and to support public financing of campaigns, i.e., outlawing Super PACs (they were a total anomaly in this regard). In 2011, they received one of those so called "national security letters" and just completely stonewalled the FBI. Thank god for this one activist mobile carrier or this case would've probably never happened.
Credo is the latest incarnation of the old Working Assets long-distance firm, if you're old enough to remember them and that helps explain their politics.
