After several months of discussion and speculation, the Microsoft-Yahoo buyout deal is apparently off. At least, that's what both Microsoft and Yahoo announced over the weekend. There is some speculation that Microsoft CEO Steve Ballmer made his announcement in order to topple Yahoo's share price, in order to make another offer at a lower price. But for now, Yahoo is saying that they have come out of this fight stronger and more focused than before. Does this mean that we will see a change in Yahoo's commitment to open source?
