I HATE auto updates, living in a part of the world with slow internet. When I am on my pc I want to do what I want to do, not wondering whether it has been infected or what is wrong with it. At the very least there should be a notification that it is being updated.
I am aware of the means of controlling the date/time of Snap updates but that is not satisfactory, because it means projecting when the pc will be free or leaving it on for extensive periods of time, merely waiting for a possible update.
One of the great things moving from Windows to Ubuntu 6 was the control over updates. At that stage it was not possible to change it in Windows.
