> Why does this tool exist and must be installed on servers?
Fads, laziness, and lack of forethought. This tool didn't exist a few years ago. Nobody stopped IT departments worldwide and said "hey, maybe you shouldn't be auto-rolling critical software updates without testing, let alone doing this via a third-party tool with dubious checks."
This could have happened on any OS. Auto deployment is the root problem.
