It depends on what distinction you’re making…

If you are asking concerning security, the answer is that it’s an insecure default that should have protected an unwitting user.

If you are asking concerning consistency with real world situations, then there is no difference and it feels like the fit is over a somewhat controversial figure (DHH) and how he created the distro’s recent release without reading any of the code himself. The counter is that no one installing a distro actually understands how their distro is configured, and trusts someone else’s judgement. Here that judgment was farmed out to AI, and while that is controversial, the uncomfortable truth is that this is how an awful lot of real people are told to configure their Docker installations.

IMO Docker running as a root daemon is a bad idea in the first place and I’d much rather use Podman’s rootless containers.
