Surprise! Seventeen days after tweeting that he had "funding secured" for a transaction to take Tesla (NASDAQ: TSLA) private at $420 a share, CEO Elon Musk called the whole thing off late on Friday night. In a post on Tesla's blog, Musk said that given the feedback he has received since his initial tweet, "It's apparent that most of Tesla's existing shareholders believe we are better off as a public company." Of course, with Tesla, the real story is often found between the lines of its official statements.
