What is the biggest DAO on Ethereum?

Could you please elaborate on what the largest DAO, or Decentralized Autonomous Organization, currently exists on the Ethereum blockchain? I'm particularly interested in understanding its scale, functionality, and the impact it has had within the broader Ethereum ecosystem. How does it compare to other DAOs in terms of membership, funding, and the types of activities it facilitates? Also, what are the key factors that have contributed to its growth and popularity? Your insights would be greatly appreciated.
