Who owns Tezos?

Could you please elaborate on the ownership structure of Tezos? I'm curious to know who exactly holds the reins of this cryptocurrency project. Is it a centralized entity or a decentralized community? If it's the latter, how does the decision-making process work? Are there any key individuals or organizations that have significant influence over the direction of Tezos? I'm also interested in understanding the role of the Tezos Foundation in this context. Could you provide some insights into their responsibilities and how they contribute to the overall governance of Tezos? Thank you for your time and assistance in clarifying these matters.
