Who owns Ethereum?

Could you please clarify for me who actually owns Ethereum? Is it an individual, a group of individuals, or perhaps a larger organization? I'm interested in understanding the ownership structure of this cryptocurrency and how it might impact its value and overall functionality. Additionally, is there any way for an individual to become an owner or stakeholder in Ethereum? I'm quite fascinated by the concept of decentralized ownership and would love to learn more about it in the context of Ethereum. Thank you for your time and assistance.
