Who runs the Ens?

Who exactly runs the ENS? Is it a centralized entity or a decentralized network? Could you elaborate on the governance structure of the ENS? Who are the key decision-makers? Are there any specific organizations or individuals responsible for its day-to-day operations? Also, how does the ENS ensure its security and reliability? Is there a team dedicated to maintaining and updating the system? I'm curious to know more about the inner workings of the ENS and how it manages to function effectively.
