I don't follow. Windows 10 has an action center, it shows everything pending. If there are security updates and they're frozen or pending restarts they show up in there if you misted the toast notification. Nearly all OS's have the problems of security updates being hidden unless they're forced (like a phone). OSX you have to click update inside the app store, Linux you have to check apt-get / yum update or whatever it is you do, brew you need to "brew update" - humans need to be part of the equation in some fashion.

I think the biggest thing is that people should care about being secure.. care enough to check for updates and be a part of the community they choose to be a part of - be it Linux/windows/osx/android/whateverthe* you want

For what it's worth, as of 16.04 Ubuntu automatically installs security updates: https://blog.appcanary.com/2016/unattended-upgrades.html

In snapcraft, all updates are automatically installed: https://docs.ubuntu.com/core/en/reference/automatic-refreshe... https://www.youtube.com/watch?v=DLxqdf89hRo

only if you leave unattended on.. most server admins turn that off so servers don't change out from under config management.
