That's just patently false.
> Importantly, HyperCore does not rely on the crutch of off-chain order books. A core design principle is full decentralization with one consistent order of transactions achieved through HyperBFT consensus.
as an operator you don't even get the real validator / node binary directly, nor can you control which version to run.
all you can do is run their visor, and they push out whatever proprietary blob they produce and restart "your" nodes at their command.
The basis of decentralized software is open-source. Otherwise a centralized authority can just push an update to, for instance, blacklist addresses.

"For lowest latency, run the node in Tokyo, Japan."
Decentralization means to run all of the closed-source nodes in the same AWS datacenter!
