So macOs just lied to me. I went into storage and recommendations. And saw this
Which clearly says store all files photos and messages in iCloud and save space on Mac automatically when it's needed.
As soon as I accepted this recommendation what it actually did is this
Which reads quite the opposite "The full contents of iCloud drive will be stored on this mac" ?!?!?!
I managed to turn it off but now I have these massive downloads pending and not doing anything.
How do I remove them?
