I agree. There are many reasons why Google may have rejected the offer to bid jointly – and the offer's terms aren't clear at all. Also, posting private intercompany emails is unprofessional, even in response to a misleading tweet from your competitor. Even less professional is the "divide and conquer" positioning that characterizes Google's lawyers as lacking internal communication/coordination. Frankly, I get a bad smell from either side in this latest Twitter slapfight between MSFT and GOOG.
