Why the conviction moved

• Aug 22
  Strengthened +3

  OpenAI's zero-retention offer on frontier models and Anthropic's retention-rule reversal both reduce the pool of stored conversations available to investigators and litigants. Vendors are engineering discoverability out of the product, which is the defensive response the thesis expects as chat logs become routine evidence.

• Aug 21
  Strengthened +4

  OpenAI is engineering abuse detection that works without any human-readable log, explicitly to keep zero data retention intact for frontier-model customers, while Anthropic moves the other way with a 30-day business-log retention window. Vendors building around 'no readable record exists' is a direct response to logs becoming discoverable and subpoenable, and it pushes sensitive workloads toward zero-retention tiers.
