What a load of condescending twaddle especially the last bit. It isn't an unreasonable requirement at all to have control over updates.
Interestingly one of their design goals for updates is "must be deployable with minimal impact on users" not doing so well on that front by any metric... maybe time to go back to the drawing board.
(As an aside, critical security updates aside, this tablet I'm on right now hasn't had any other updates since May 2014 and worked fine and done everything I've asked of it).
I'm not even sure what your point is with legacy software and home users - so many home users will be needing to use legacy software for a variety of reasons whether it is an old mod for a game or educational software that has long been abandoned with no immediate replacement and so on.
I don't think anyone has complained about Windows 10 being "too hard" to use ever in the 1000s of posts here - you are completely mis-reading what people are complaining about.
To break it down a bit when it comes to the start menu you tend to have 3 main types of user:
-Those that largely use search
-Those who like all the options up on screen making full use of the screen estate of their monitor to find what they are looking for
-Those who like a concise, minimal, organised menu that doesn't distract from whatever they are working on and can switch to and from it with minimal effort
For any of those users it is harder if they are forced to use one of the other types that doesn't mean they find the OS "hard" to use and no matter how much they "adapt" it will still be less effective than the method that suits them most naturally. For those that like to quickly type stuff out with minimal time away from the keyboard and minimal visual/UI interaction a menu will never be efficient no matter how easy it is to use while for those who a driven by a visual experience and like to use the mouse to find what they want having to spend time on the keyboard will never be efficient no matter how easy the functionality is and this extends to other areas of the OS and in other ways.
I know what they are saying but point is you can't build any OS to please everybody, we all like different things with regards to layout, how we actually use the OS etc, in the end it's easier just to adapt and adjust to the changes then hoping Microsoft will make changes to suit YOUR needs.
Speaking from personal experience I do find it easier to adjust to the OS rather then wanting this or that changed etc, this has been my way with Operating Systems for many decades.
