One thing I will not do is willingly allow somebody else a way to deploy and execute code on my computer without my say so (which snap is).
After reading the whole thread at https://forum.snapcraft.io/t/disabling-automatic-refresh-for... and seeing Gustavo Niemeyer's arrogance (we know better than you when you should be applying updates) I will be voting with my feet and will be installing Pop!_OS instead of Ubuntu, and if snapd is present I will remove it.
The stated goal of Niemeyer, to have users use updated software, would have been fulfilled in my case if I had a way to see what updates would be applied beforehand, instead of the updates being force-installed.
Lengthy dialog with Niemeyer in the forum thread seems to have been a waste of time for all the people who participated trying to convince him to allow disabling of force-installed updates so I suggest you do the same as me and vote with your feet!
