No one owns the entire metaverse network. Metaverse is not a real physical thing that you can own. It is a virtual 3D world where everyone can participate. There are different metaverses created by different people or teams. Theoretically, the creator of a metaverse is its true owner, but that may not always be the case. In the case of the Facebook Metaverse, it is owned by the company founder and CEO, Mark Zuckerberg. Decentraland was created by Ari Meilich and Esteban Ordano for a company called Metaverse Holdings Ltd., which and a number of investors own the rights to the digital universe.
