I understand what you are saying, Wolfgang.
I think Linux needs more skills than windows to do a good amount of necessary things.
As a merely average user, I find that Windows 10 is better for me. It is an overall feeling ... hard to pinpoint which part I like the most and why. What I have noticed that it performs better than windows 7 in essentially identical conditions.
Cloud based computing is not very possible with the poor internet speed that I can avail, still OneDrive is not a big problem with that little speed. When something is uploaded there, it is as easily accessible as it is in my HDD.
About the actions without user's consent, I really dont have an idea which are those.
Rather I am sometimes annoyed as it keeps asking for permissions when I know what I am doing.
I also have the way to use a local account, so OneDrive, XBox, Skype and other similar things can easily be dropped. If I need to use those in local accounts, I have that way, too.
From another perspective, the most popular gadget of this time is an android/microsoft phone/tab. We use those devices everyday as always logged on using a google/microsoft account, for gaming, facebook, email etc. A windows phone even save the phonebook contracts as hotmail contracts!! So using a microsoft account on a desktop or laptop PC will not be a very big issue to the majority of the users. They are already habituated with this practice.
Microsoft is a business concern. They will try to maximize their revenue by keeping users connected with them, by making them use the apps from their stores (as it is done by android and apple). If they dont do it, they will earn less revenue than their competitors; which will have a big bad impact on the concern in turn. So what they are doing is good for them.
As a customer I have to decide whether it is good for me or not. Let us use the preview and judge it ourselves. It is not necessary that all our judgements will coincide. Buying their product is on me only. If I dont like their product or their way, I may keep with the old one by them that I liked; or even I may use another alternative, like Linux as you said. I really dont need to remain as a dissatisfied customer.
