Is Celo centralized?

Excuse me, but I have a question regarding the cryptocurrency platform known as Celo. I've heard differing opinions on whether Celo is centralized or decentralized. Could you please clarify? In my understanding, decentralized networks aim for transparency, security, and a more equal distribution of power, whereas centralized systems tend to have a single authority overseeing operations. Does Celo's architecture and governance model align more with a centralized or decentralized approach?
