Have you ever worked in a corporation or in government? Even moreso, have you ever worked at a secured facility of any type?
You don’t just get to install whatever the fuck you want on machines, you know? They have to go through a process, and since this is a government organization, if the law doesn’t allow them to install something like that on a thin client, it’s kind of pointless to reference.
I’ve worked a shitty corporate job where I basically had no power and I had to get approval from a couple different teams for something like Microsoft PowerToys, which is free and made by Microsoft.
