(b). Google is attempting to create subterfuge to ward off the Antitrust suits they are facing. If you are following that development, then you know that the FTC just hired Beth Wilkinson. Beth is a former DOJ prosecutor, who has never lost a case. When the FTC made that move, it was letting Google know that they are in fact going to be sued by the FTC much like the case of The United States vs. Microsoft. Google is also facing the same type of lawsuit in Europe. If you recall, when Microsoft lost that lawsuit, it opened up the doors for companies like Google to sprout up.
Google is also in a lot of copyright infringement lawsuits too, notably with Oracle. Oracle could do some real damage to Google if they win.
