> 1000 validators is very centralized. All you have to do is bribe 2/3rds of them control the chain.

The network can be halted when 1/3rd of the nodes collude. To my knowledge this allows you to halt the network but not reorg blocks or double spend.

> Solana scales through centralization, not new ideas in blockchain scalability.

Nonsense. They made different tradeoffs than Ethereum and a number of innovations were made possible by those different decisions.
