AOL the New Target for Microsoft?

To avoid being swallowed by Microsoft, Yahoo decided to approach AOL and offered a merger between both companies to become to big to be eaten by Microsoft. The Redmond's giant probably frustrated of seeing Yahoo resisting in such way, started discussing of a possible acquisition of AOL with Time Warner. The main goal of this new maneuver is to further isolate Yahoo, and stress their shareholders of seeing Microsoft leaving talks for the second time and most likely definitely. Is Microsoft acting this way to push Yahoo's shareholders to kick out their CEO, and directly discuss with Redmond’s giant about a juicy take over, or is Microsoft really tired of negotiating with Yahoo, and favoring a more friendly acquisition with AOL?
