## Nauti's Take

This looks bigger than Fable 5 and Mythos 5. Governments can have legitimate reasons to act on real security risks, but a full cutoff without public technical evidence moves a lot of power into opaque channels. For customers, the practical lesson is blunt: building critical workflows on closed models also means accepting political shutdown risk.
