I've never been particularly fer or agin the Kochtopus. I like some of the people, organizations and causes they fund; others, not so much. If they sent one of my own projects a check, I'd consider what strings might be attached before cashing it, but I do that with every check.
Anyway, the "evil left-wing media" have been up in the Kochs' stuff this week. If any of the "revelations" involved are particularly damning, they're probably to be found in this piece from the New York Observer: "7 Ways the Koch Bros. Benefit from Corporate Welfare."
