How decentralized is DAI?

Could you elaborate on the level of decentralization exhibited by DAI? I'm particularly interested in understanding how its governance structure and issuance mechanism contribute to its decentralization. Additionally, I'd like to know if there are any centralized entities or individuals with significant control over DAI, and how this might impact its overall decentralization. Your insights would be greatly appreciated as I'm trying to gain a deeper understanding of this cryptocurrency.
