Free Windows 10 will be till RS1, to get the next version will have to pay update service fee.
about how its inevitable OS, Internet explorer is good example, its become obsolete and didnt fit to UX
today chrome is mainstream, mb Android for PC by google ? will change the OS distribution ?
Microsoft doing it again apply their policy like they did with IE, updates complication decrease security , no updates for old OS, no addon
and going with old engine, customer satisfaction will degrade, Someone else will see it as opportunity to make a slice in MS market
