I can confirm that dragging between devices does 'copy' by default. And dragging from iCloud to local drive does 'move' by default.

In general 'modification' by default is bad.

It is what you expect on local drive. Windows do the same.

It is. That's why I quoted 'modification'. It's not a sensitive issue if it's easy to undo. Which is the case on a user selected files on a drive (unless it's between naive FS or sluggish drives). On a remote system, you'd have to reup the whole thing.
