Is Wormhole decentralized?

Could you please elaborate on the question, "Is Wormhole decentralized?" I'm interested in understanding more about the characteristics of Wormhole and its relationship to decentralization. How does Wormhole operate? What are the key features that contribute to its decentralization, if any? Also, are there any aspects of Wormhole that might suggest it's not fully decentralized? It would be helpful if you could provide some insights into this matter. Thank you for your assistance.
