I guess they are just used to getting what they want and they want Yahoo even though Yahoo’s board rejected their offer because they thought Microsoft undervalued the stock. But Microsoft doesn’t look like they’re going to let a little thing like that stop them from assimilating Yahoo. Don’t they know that “resistance is futile?”

In a sign things could get messier, Microsoft didn’t say it would be immediately raising its bid, as expected by some financial analysts. It also called Yahoo’s move “unfortunate” and reiterated an intention to acquire Yahoo by any means necessary.
“As we have said previously, Microsoft reserves the right to pursue all necessary steps to ensure Yahoo’s shareholders are provided with the opportunity to realize the value inherent in our proposal,” Microsoft said in a statement.
“All necessary steps” includes several options, including a soft sale to Yahoo stockholders that would encourage them to persuade Yahoo’s board, a tender offer directly to Yahoo stockholders that would have a more forceful effect because it would enable stockholders themselves to sell directly to Microsoft, a hostile takeover of Yahoo’s board during the board’s elections next month, and a higher bid.
That last option seems increasingly unlikely to happen soon. In Microsoft’s response, it calls its proposal for Yahoo “full and fair” and says that it offers shareholders “superior value.” “The Yahoo response does not change our belief in the strategic and financial merits of our proposal,” Microsoft said.
