What's the threat model here? Is the potential adversary able to do MITM?

- The DHT does not anonymize the poster ipaddr, the post contents, posting time and other metadata

- same for the reader ipaddr, what was reading, and when

Based on the timing, I would imagine the threat model is ad purveyors taking over a previously relatively open application provider and engaging in soft-to-hard censorship of controversial topics until the only acceptable content is tweeting about how happy you are about #brands and #socialjustice.

That isn't a threat model for this but speculation that this is a mitigation of a threat in twitter's threat model.

It isn't clear what threats the design of this system guards against or that much thought was given to the types of attacks so much as to create something shiny and decentralized.
