Re: Is this really Microsofts POV?
Pretty much, it's about the money and the route to it.
If you look into Microsoft's financials for quite a long time now, whatever division the Office suite is in is the one that's made the most money. The OS division, while a valuable enabler and lock-in aid, has been making less and less money over time. With other OSes being given away for free, the ability to sell "just" an OS is a harder and harder prospect particularly when the previous OS worked and continues to work fine. Microsoft are also finding this with the Office suite, because any further functionality they add is beyond what most users want or care about therefore selling a new version is becoming harder and harder.
The result? OSes are effectively free and while Office suites are, for the time being, a source of income as these become more commodotised this income will dry up and they'll become effectively free as well. However just because something isn't sold doesn't mean that it isn't valuable as an enabler for other sales therefore Windows 10, even if given away, has considerable value in pushing Microsoft's services and applications. Take Microsoft Office, currently it's arguably the best office application suite by a reasonable margin, or at the very least has enough remaining lock-in to keep users "loyal", however even this is being eroded by the likes of Google Docs which is given away for free. However both are being used to gently (or not so gently) push users into a cloud subscription - as in a perpetual, regular income.
