Sysadmins very commonly make a lot of use out of automating things with Powershell and various utilities that work with it.

Given that a pretty decent sized portion (I’d assume at least, no numbers to back that up sadly) of the Linux user base tends to be “cut from the same cloth” in terms of having the passion to automate (and heavily customize) their system - I would think this is why you see this sentiment repeated often.
