It has 1200 validators, compared to 260,000 on Ethereum, and it's basically impossible for anyone to run a node at home because it requires 300Mbps+ internet connection to run one.
The problem with this you can't yourself verify what is happening on the chain, you have to trust that the node operators are acting in good faith and not censoring transactions or forming cartels to manipulate history.
This is ok if you only have a small amount of money or are using it for games or something that doesn't really matter. But it'll never be able to run the global financial system or store things of large value.
The connection bandwidth, and to a lesser extent the computer hardware, push validators to run in data centers. The reliable fat bandwidth is a big requirement which drives centralization.
If most Solana validators run on AWS, then it is as centralized as the AWS datacenters. I think they have 50+ facilities now.
