Taibbi argues that the move is designed to protect investment banks from bloggers who are exposing the companies’ stock market manipulations

Blogs such as Zero Hedge have been using NYSE data to argue that Goldman Sachs now has an almost unfettered ability to control stock prices.

Goldman Sachs is singled out because the investment bank’s share of principal NYSE trading has gone from 27 percent at the end of 2008 to fully 50 percent of trades in recent months.

The fact that Obama is allowing this nonsense to happen is proof positive that he isn't left wing at all.
