Remove "Add shortcut to OneDrive" from Sharepoint Sites

This feature is completely pointless and the inability to turn it off is causing big problems for us. Users don't understand what the feature is for, they click it to see what it does, and then the OneDrive "Sync" connection they already have set up stops working. I don't see why the two things have to be mutually exclusive in the first place, but if it's one or the other, we need a way to turn the "Add a shortcut" thing OFF.

I upvoted the https://sharepoint.uservoice.com/forums/330318-sharepoint-administration/suggestions/42090253-disable-add-shortcut-to-onedrive-for-a-document; now I suppose it's just a matter of sit-and-wait for six years for Microsoft to do something about it, like everything else that ends up on UserVoice.
