I wouldn’t recommend Docker for a production environment either, but there are plenty of container-based solutions that use OCI compatible images just fine and they are very widely used in production. Having said that, plenty of people run docker images in a homelab setting and they work fine. I don’t like running rootful containers under a system daemon, but calling it a giant mess doesn’t seem fair in my experience.
This looks loke something stupid, but it doesn’t really look like KKK costumes. I could understand if your point is that even a vague resemblance might be in poor taste, but “closely resembling” seems like a stretch.
