Hi @NIEB (Nicolai Errebo Birch)
In the three articles you provided above, I notice that SharePoint Server 2013 is not included in the Extended Security Update (ESU) programs:
The Extended Security Update (ESU) program is a last resort option for customers who need to run certain legacy Microsoft products past the end of support. It includes Critical* and/or Important* security updates for a maximum of three years after the product's End of Extended Support date.
Actually, we need only view this article to know the end date:
https://learn.microsoft.com/en-us/lifecycle/products/sharepoint-server-2013
As it is described in it, Mainstream End Date is Apr 10, 2018, Extended End Date is Apr 11, 2023.
We could not receive security updates for SharePoint 2013 after end-of-support (11/4-2023).
