DevOps as a practice isn't wrong, of course. Sysadmins scripted and programmed since the dawn of the silicon Pleistocene. But if every small company hires someone with that specific job description, well, you have to spend your 80+ startup hours somewhere.
you can't just drop a sentence like that and not elaborate on it - unless you want to offend somebody.
Each resource hungry "DevOps" tool has its place and has its worth. They're just often misused. A small IT firm with <10 Hypervisors won't need openstack for example. Thats only worth its maintenance if you're working with tens or hundreds or hardware machines.
And a webapp which consists of <10 services probably doesn't need service discovery and advanced de-/commissioning of containers/vms. Administering hundreds of microservices without that is borderline impossible however.
