I was at Microsoft when Nadella took over Azure but I left before he became CEO. While it's true that Microsoft was taking steps to open source products under Ballmer, it was despite him, not because of him. There was an incredible amount of red tape, dragging of heels and internal fear uncertainty and doubt. Even internal only projects to synchronize open source practices among divisions were an uphill battle. If anybody deserves credit for Microsoft's open source efforts at that time, it's Sam Ramji who should get the credit, not Ballmer. From the outside, Microsoft under Nadella has all the stops removed. This all lines up with a quote that I heard from Nadella 3rd hand: "We [Microsoft] can either push the 'One Microsoft' vision, or we can make money."
