## Why It Matters

Stratechery's framing: Muse only wins if it can act inside Amazon, but Muse skips Amazon's ads — so Amazon's physical-world delivery network lets it block Meta and absorb the cost. Meta's likely counter is a Walmart partnership.

## Key Findings & Analysis

### The block and the standoff

- Amazon blocked Meta's new agent, Muse, according to Stratechery's weekly roundup. Stratechery calls the conflict the start of an “aggregator war.” — Stratechery (analysis, not confirmed by Amazon or Meta in the excerpt). The logic Stratechery gives: agentic shopping is a strong use case for mundane errands, and Amazon's reliable delivery is the best available utility for it — but Muse doesn't show Amazon's ads. Amazon's differentiation sits in physical-world investment, which is why Stratechery says it can afford to block Meta (analysis). To route around that, Stratechery says Meta needs Walmart (speculation). Stratechery also notes open threads: “Muse and Expedia,” and the question of where Google is (analysis). In the same roundup, Stratechery flags GM's reversal on CarPlay after three years of customer and dealership backlash — a reminder that platform lockouts can unwind.
