The goal is to fully control your environment and not to expecting some unexpected updates.

User is the one who must choose update policy. If user is choosing to not update then it's their own problem and no manufacturer has the right to deside otherwise.

Automatic updates are a good default, you can always disable them if you don't want them.

Good default is to ask users about their preferences explicitly and not to hide that kind of settings anywhere.

In the past I would have agreed with you. Sadly there are "updates" which remove functionality.
