Anyone can declare they have a sybil proof network if they have the power to declare everything that invalidates the proof as being non-sybil.
It might be a productive discussion if there could be an agreed upon definition of Sybil. The "proof" requires Sybils to inject an excess hop but no rationale as to why they would do so.
Saito is as vulnerable to Sybil attacks as Bitcoin is to miner concentration. In an open network cooperating nodes will always have an advantage over independent nodes. You cannot distinguish between the two in a permissionless network.
