Tangential, but this made me reflect on how "good"/"nice" Ballmer, and Ballmer-era MS, was in a very relative sense. This is slightly startling considering how my mental image of either Ballmer or MS is not great. But now looking back it does feel like relentless anti-competitiveness lessened a bit during that era, and lot of good stuff happened then. Windows 7 probably will go down in history as the pinnacle of traditional desktop Windows, MS giving up on IE gave room for Firefox and (unfortunately also) Chrome, lot of previously proprietary stuff got documented and published (SMB and Office formats comes to mind), and there were some nice product developments.
In contrast Gates era Microsoft was very much characterized by strong-arm tactics and throwing their weight around. And now Nadella era feels very aggressive again, pushing the company forwards no matter what; in some ways maybe less vindictive and direct than Gates, but still definitely not nice.
