Meta: What Happens When AI-Driven Cost-Cutting Guts Integrity Engineering
Summary
Detailed first-hand account of Meta forcing 30–50% of engineers into ADO org for AI training data labeling, gutting integrity/security teams. Instagram integrity team lost 30–50% to forced reassignments. CISO resigned after a security outage. The follow-up piece hypothesizes that the major Instagram security outage was caused by integrity team collapse + over-reliance on AI code review. Developer documentation team went from 200 to 9 people.
Why this signal
A concrete cautionary tale about what AI drift looks like at org scale — structural erosion of the teams responsible for catching failures. The Instagram outage hypothesis is a specific, attributable failure mode directly relevant to Neo's #5 focus area. Shareable with team as 'what not to do.'
