More on Anthropic's Scion ripping off Mononoke

Anthropic's Scion version control system is accused of intentionally copying Meta's Mononoke system, with similarities extending far beyond the concept of derived data to include identical data models, nearly identical changeset structures (with "Scion" even reversing the syllables of "Bonsai," Mononoke's changeset name), and comparable server-side APIs. The author, who worked on Mononoke's development, received private confirmation of the intentional copying after initially giving Anthropic the benefit of the doubt, noting that the Bonsai data model was a contrarian and novel approach in 2018 that required solving several hard problems.
