It was pulled because the two people (a couple named Herb and Marion Sandler) who had sold a sub-prime origination bank in California (Golden West Financial, purchased by Wachovia in one of the most stunningly stupid deals of the sub-prime melt-down) threatened to sue NBC for libel, not because of Soros. The Sandlers are not “public” people, so NBC’s parody of their sale of the bank, and the subsequent melt-down of Wachovia being presented as being the fault of the Sandlers was libelous.
But it certainly does make sense.
