What is the definition of a "standard security update"? What other classifications are possible?

Since recently upgrading to 20.04 I see informational messages after running apt update similar to

46 upgraded, 5 newly installed, 0 to remove and 0 not upgraded.
31 standard security updates

Googling has failed to turn up the definition of the phrase standard security update. What is it? And, are there non-standard security updates? What possibilities are there?

Seems to a part of ubuntu-advantage-tools to distinguish between freely available security updates (standard) and ESM (paid, later, actual for 16.04 LTS).

May be removed by removing special UA hook by

sudo rm /etc/apt/apt.conf.d/20apt-esm-hook.conf

Above will transform

42 upgraded, 5 newly installed, 0 to remove and 0 not upgraded.
29 standard security updates

to normal traditional behaviour

42 upgraded, 5 newly installed, 0 to remove and 0 not upgraded.

All this UA ESM stuff on supported Ubuntu versions smells like big BUY word with capital letters.
I found this unacceptable. Especially the viral behavior of UA:

$ sudo apt autopurge ubuntu-advantage-tools
Reading package lists... Done

The following packages will be REMOVED:

After this operation, 6 687 kB disk space will be freed.

Abort.

I have reported a bug 1950692 about ubuntu-advantage-tools "integration".

Just to confirm, I dug up an old 16.04 VM that has ubuntu advantage enabled on it. Instead of `standard security updates` it says `26 esm-infra security updates` Well done!

You're right about standard security updates. Those are delivered in the Ubuntu Main respository for the initial 5 years of any Ubuntu LTS release. For example, Ubuntu 20.04 LTS benefits from it until 2025.

The ESM security updates are indeed in a different category - they go beyond standard security updates. The access requires a subscription, but it doesn't necessarily mean that you will have to pay anything. Anyone can get a free subscription for personal use.

Full disclosure, I am a product manager at Canonical.

How about giving us a simple way to turn ubuntu advantage off for supported systems? Stopping it is turning into a game of whack-a-mole.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
