I assume you mean podman?

The first two are just kind of the nature of containers on linux, and applies to any container technology.

Podman does allow you to run it as a non-root user (with some limitations), that was in fact one of the biggest motivations for making podman. This wasn't possible at all in the early days of docker, it wasn't until linux introduced user namespaces, where the root user inside the namespace mapped to a non-root user id outside the namespace that non-root conatiners were possible.

And podman, unfortunately IMO, is also written in go.
