Who controls Ethereum Classic?

Could you please elaborate on the question, "Who controls Ethereum Classic?" I'm curious to know if there's a centralized entity or group of individuals responsible for managing it. Also, is there a governance structure or mechanism in place to ensure the stability and security of the Ethereum Classic network? I'm interested in understanding the decentralization aspect of this cryptocurrency and how decisions are made regarding its development and updates. Could you provide some insights into this?
