Key Structural Insight

Engagement is not lock-in. Highest time-spent but moderate B because algorithm, not graph, drives retention.

Scoring Rationale

Highest time-spent (1hr 35min daily). But algorithm-driven, not graph-driven — competitor with equal algorithm could substitute. Creator lock-in stronger than consumer. US ban risk.
