I'd assume anybody criticizing kubernetes isn't a huge docker fan either.
I see both used much more as dev ops tools rather than real cluster management.
Particularly questionable in organizations that may not have any in-house tech expertise. Some contractor, who may be the only programmer involved at a given time, comes in and sets everything up the kubernetes/docker way. From now on you'll always need kubernetes-enabled devs to maintain your thing.
Happened to somebody I know. They believed they had a "cluster" with different "servers" but it was a single machine. Then I had to explain why they cannot just FTP into the server, upload plugin folders (like some tutorial asked) and expect it to work. Nor did I have enough time to help out since who knows how these dockers mount folders, what's the latest "best practice" or what the dev who maintains it prefers. There's no way they'll ever need more than one machine. I'm pretty sure the system in question does not even have a good cluster story in the first place, so at best you could scale the database (which usually can do clusters well without 3rd party tools).
