There’s never been a time where a sane person would use a Windows server for example
I dunno if it was sane, but my employer has been deploying Windows servers in industrial environments where the “operator” are technicians (non-IT) without access to remote support. With a Windows interface at least they are usually able to navigate the system and troubleshoot when needed without Linux experience (which they never have).
Imagine writing your breakup in Office 2007… I mean, at least use a free and open-source software like LibreOffice.
