I am sure the Chinese and Russians are happy with the decision of the Navy.
I’ve heard anecdotal stories on FR and in my day-to-day where XP runs some machine or system that cannot run on modern operating systems. Granary systems, T&D machines, factories, forges, etc., they all use XP in some way, but the key there is that the machines are not connected to a network. They’re standalone systems running some software that does what it does. If it works, leave it alone, fine, but as soon as you introduce a network connection, a compromised USB drive, a compromised CD/DVD, or anything that might interrupt or “update” normal operation of that system, you have fundamentally changed the operability of that system and potentially compromised its safe use.
