I'll tell you what's wrong here : Docker is a fantastic technology but it simply couldn't find a suitable market tactic.
Now it resolves to this shitty practices. I don't even know how you can begin to think that it would add ANY burden to them NOT to run the update on your computer.
And here is my problem : It's my computer, I decide what is ran on it or not.
Next day we have some idiot getting keys on the docker update system and we simply have built a technologic crash because suddenly nobody can decide wether that update is ran or not.
Keeping control away of the user is the most stupid thing there is.
