schizoidmanWindows 11 is now automatically enabling OneDrive folder backup without asking permission
I once turned that feature on thinking it was an actual backup (copies of my files in the cloud), I remember how angry I was when I found out it wasn’t a backup after all and just removed your files from your computer and only made them accessible online.
You can see their strategy at work here.
It is possible to keep individual files on the local hard drive with different settings (that in my experience never seem to stick past updates).
The default, though, is to take everything on your computer off of your computer, put it into the cloud (their computer), and recommend you pick and choose which ones stay on your computer. In essence, they want you to think of your computer as secondary to their computer. An extension of it.
There is no “your computer”, it’s just the computer you happen to be logged into at the moment.
