How good is all that off the Window ecosystem, and for how long has that been the case?

Microsoft institutionally had a "does not play well with others" attitude to the point of stark figurative murderousness as we saw in SCO v. The World during the Ballmer years ... and as for "robustness", the one signal failing of Nadella is quality.... I could make a case it's as risky an option in the medium and long term as these other ones, and confidently state it will take at least a decades before a lot of us maybe trust Microsoft's good will outside its Windows ecosystem, hindering wider adaptation.
