It's not that easy. Because that shit comes back, usually with the next update.
I've prepared windows machines in a B2B IT support firm for our customers. Over very few years it became very quickly progressively harder to install windows without a network connection, set up local user accounts, debloat everything, etc.
We even had customer's employees paying us money to untangle their private machines from that MS BS, and it took us a few hours per device.
And don't get me started on "I saved a file to OneDrive but can't find it there". That happened often and wasn't always user error (like, 50/50)
Also, let's be real here. This is not a problem for the vast vast majority of users.
Yes it is. Whether they realize it or just think it would be more of a hassle to solve it and instead just roll with it is another thing.
