A bit reductionist. IIRC the main reason Docker was phased out because Red Hat wanted to push rootless, daemonless containers, which required CGroups v2, which Docker didn't want to support for the longest time. Since both versions of CGroups can't be enabled simultaneously, and no distro wanted to go without Docker (or at least Docker-like) functionality, CGroups v2 was left in permanent stasis, and so Red Hat started Podman to break the deadlock. There were a laundry list of other technical disagreements (mostly around security) but that was the primary one.
And then once Red Hat distros switched over to CGroups v2, which Podman enabled them to do, it meant that Docker wouldn't really work all that well anymore until they eventually switched to CGroups v2 also (which they eventually did a few years later). So that's why it got removed from the repos, at least originally.
