I agree with the initial assertion as to how companies work when they start to grow to medium or larger. The rest, though, feels an awful lot like projection on the parent's part; someone's an insecure admin or programmer reveling in their superiority at a moderately sized company -- not meant to be an ad hominim but you're really specific there, buddy.
The enterprise is about supportability, scalability, and ease of maintenance. Officially support software and common tools/platforms/SOPs are a must unless we're building something brand new from scratch. DIY charoot jails may work just fine... until the two admins who really know it go on vacation or quit or get fired for mining BTC on company gear. Now Johnny-New-Hire needs to unravel it, and it may not be documented well, or even work that well without an admin kicking it occasionally.
Were I to put a job advert out for DevOps roles needing Docker I could usually get someone with a base level of competency, and get them reasonably quickly. Likewise if I need to outsource this to contractors or even offshore budget IT support it's a lot easier to find a Docker guy then it is running someone through whiteboard exercises to figure out how much they know about jails and makefiles. And if we're way out of our league with issues there is Enterprise Docker which is expensive but gets us official support from Marentis (or whoever owns them now), which may not be justified in terms of cost, but absolutely makes management sleep easier knowing we can escalate things if we can't fix it internally.
