I'm confused about this assertion. Managing fleets of thousands of Linux machines via declarative role-based configuration management is completely normal. Linux also has a way better story with updates that activate instantly (occasionally requiring 10s to reboot for a kernel update) with easy rollbacks if something goes wrong (e.g. nixos).
What exactly does Windows have that makes it easier to manage machines?
> What exactly does Windows have that makes it easier to manage machines?
A large marketing budget and sysadmin / devops outreach in a way that no single and all Linux distributions collectively haven't matched. Integration of things into a cohesive single tool instead of a grab bag of tools that move from hyped to normal to unmaintained in a number of years.
