Who controls ETH?

Could you possibly elaborate on the question of who actually holds the reins of ETH? Is it a centralized entity, a consortium of developers, or does it belong to the vast community of crypto enthusiasts? Are there any governing bodies or institutions that have direct influence over its operations? Additionally, how does the decentralized nature of ETH factor into this, and does it mean that no single entity can truly claim ownership or control? Furthermore, are there any mechanisms or protocols that help maintain the stability and security of ETH, and how do these contribute to the overall governance structure? It would be fascinating to understand the intricate web of relationships and responsibilities that shape the governance of ETH.
