Looks like fud to me. The keys are for the people running the network. Haveno decided not to run a network and just release software. If they had run a network these would be their keys instead.

Deanonymizing tor Monero nodes… This is not haveno or reto specific. Haveno exacerbates it by increasing the number of Monero nodes on the tor network, that’s all.

Looks like a nothingburger. Could reto be a honeypot? Sure, maybe I guess. But a honeypot for what? What information are they collecting? What are they collecting that they’d need to run a haveno network to collect?
