ok, the software is free... However, installing and supporting any software takes time and money to do, no matter how free the updates are. You might get away with a quick "sudo apt update" and "sudo apt upgrade" on you own PC but in an actual critical working environment it has to be done safely, that means taking heroic measures to ensure business continuity and data integrity. That means upgrade planning, backups, stage environments, and substantial testing. Then you upgrade the production system.
Anyone reading this with any experience managing any kind of software in an enterprise environment would realise the paying £8000 for an upgrade to an organisation the size of the NHS is an absolute bargain.
I doubt most people here have been responsible for a headline in the national news "NHS System down for 48 hours" - these guys probably cut corners and are now not getting any sleep and have had 10 years knocked off their life after running those two aforementioned commands.
Software costs money and if is does not then lives can be lost.
