Although I generally agree with the generalities of the article, and I share the author's "on premise" philosophy (and recommending outsourcing when it seems an obvious fit for what they're asking on-prem), being a sysadmin myself, I can't help but smell a false dichotomy. Running something well may not be trivial, but it may actually be easy enough. If someone only has one or two such services that are critical to their business, that could be OK. Also, many of the example of maintainability don't necessarily apply if the services themselves are low volume and/or limited exposure. For example, a DNS stealth master, and maybe any internal/on-prem DNS servers (but anything external is outsourced) I would argue is trivial compared to full outsourcing.
