Is IoTeX decentralized?

I'm curious to know, is IoTeX truly decentralized? I understand that blockchain technology is often touted for its decentralized nature, but with so many projects claiming to be decentralized, it's important to dig deeper. Does IoTeX have a robust network of nodes that are spread out across the globe, ensuring that no single entity has control over the network? Are there measures in place to prevent centralization over time, such as incentives for node operators and mechanisms to ensure that power is evenly distributed? I'd appreciate it if you could provide some insight into IoTeX's decentralization and how it Stacks up against other projects in the space.
