++ have found some interesting info on the downgrade of the Windows phone business on Wikipedia (Windows 10 mobile Wikipedia page) ++ so it was clear that the decision to abandon the Windows phone ship was taken as early as 2015 & this explains why the advertising/ launching video of MS Lumia 950 (XL) has the music words "the SUN goes down" ++ & so it's very possible that the CEO change in 2014 had this main strategy change at its core & was the core cause why the Windows phone enthusiast CEO was dismissed & there was a great dispute between Gates & the CEO & of course Gates imposed as always until then the Gates view/ way in the company, but later on Gates will have to leave the company & so along with Windows phone's downgrade, 2 of the key historic CEOs have experienced a place outside the MS leadership, but these former CEOs are still active in other fields.
