It's mandatory, on the orders of a senior manager who has no background in software development, for all developers in my department to have a Copilot subscription. I've never used it for anything, and I imagine it's the same for most of my colleagues(we do highly specialised embedded development with in-house custom everything - compiler, standard library, operating system, hardware), and it seems no-one is interested in whether it's used or not.

Consequently Microsoft is being paid $240 a year per person to do nothing whatsoever, which is surely a great business for them.
