Artemis is a joke. You can tell this is politically motivated by their stance on SLS. If they were serious they would give Spacex the SLS contract for being years and years behind schedule.

ULA has been operating for many, many years (Atlas/Delta, now Vulcan Centaur), RocketLab has been putting up small payloads for the last few (with Electron, someday Neutron perhaps), and BO seems close to having New Glenn flying real missions this season. But yes, one hopes that the others can become competitive on price eventually.
