Is Kusama decentralized?

Could you please clarify for me if Kusama is indeed a decentralized platform? As a cryptocurrency and finance practitioner, I understand the importance of decentralization in ensuring security, transparency, and immutability of blockchain networks. With Kusama's stated goal of being a canary network for Polkadot, I'm curious to know if it follows similar principles of decentralization, allowing for a diverse and autonomous network of validators and stakeholders. Is there a clear mechanism in place to prevent centralization of power or control within the Kusama ecosystem?
