Why this is in the vault
Weekly "This Week in Stratechery" curation issue (2026.39, "Begun, the Aggregator Wars Have") — pointer to the week's bundle content, three of whose four headline Stratechery pieces are already filed. The one genuinely new item is Andrew Sharp's GM/CarPlay vignette, which resolves a three-year-old prediction with a live proprietary-lock-in-vs-interop data point.
Curation section
- Meta vs. Amazon (Ben Thompson) — synthesis blurb tying together this week's two Stratechery Updates: Muse (Meta's shopping agent) is a strong fit for handling "mundane but necessary" tasks, but Amazon can't let it in for free because Muse doesn't carry Amazon's ads; bridging that gap needs Walmart. Content already vaulted as its own pieces (see Related).
- GM Bends the Knee to CarPlay (Andrew Sharp) — new, not filed elsewhere. Three years after GM's controversial break from Apple CarPlay to build proprietary in-car software (chasing exclusive access to driver data), GM has now announced it is re-integrating CarPlay after sustained customer and dealership backlash — vindicating Thompson's original skepticism (aired on Sharp Tech at the time) over Sharp's initial "not sure it'll be a problem" take. Discussed further on this week's Dithering episode ("GM and CarPlay").
- Profiling the Profiler (Andrew Sharp) — teaser for this week's Stratechery Interview with Colossus EIC Jeremy Stern; Thompson calls him "the best profile writer working today." Content already vaulted as its own note.
- Also linked in this issue (already vaulted): "Frontier Overhangs," "Amazon Blocks Muse, Amazon's Moat, Aggregator v Aggregator," "More on Muse, Amazon, and Walmart; Muse and Expedia; Whither Google?," "An Interview with Colossus EIC Jeremy Stern About Profiling Mark Zuckerberg."
- Bundle round-up (not vaulted individually — self-cross-promo of sibling Passport-network products, same publisher, no paid third-party sponsor): Sharp Text ("Too Many Stadiums with Roofs"), Dithering ("GM and CarPlay," "Muse Delivery Vehicles"), Asianometry ("Intel's Optane Memory: A Promise Unfulfilled," "High Bandwidth Flash Is Coming"), Sharp China (Xi Jinping DC-visit episode with Bill Bishop), Greatest of All Talk (NBA preview), Sharp Tech ("Three Weeks of Meta Momentum, The Ultimate Muse Upside, A King Kong vs. Godzilla Aggregator War"), and the week's Sharp Tech video on why Anthropic/OpenAI can't unilaterally slow down.
Mapping against Ray Data Co
The concrete connection is the GM/CarPlay item: it's a three-year, real-world resolution of the same interoperability-vs-proprietary-control bet that [[2026-09-22-stratechery-amazon-blocks-muse-aggregator-moat]] and the Salesforce item in [[2026-09-18-stratechery-doomforce-weekly-digest]] are both arguing in real time. GM traded a worse, disconnected in-car experience for exclusive driver-data access and held that line for three years before customer and dealership backlash forced a reversal — the same commoditize-or-get-commoditized dynamic behind RDCO's own bet, per [[project_l5_north_star_strategic_direction]], that agent capability (not a proprietary UI or data layer) is what wins as the interface layer. It's a useful data point on time horizon: a proprietary-control play that visibly degrades the immediate user experience can survive for years before it fails, but it does fail once a workable standard is available and customers can feel the gap — worth keeping in mind before RDCO's own agent work (Channels, or any client-facing agent surface) is tempted to trade interoperability for a proprietary data hook. The Meta-vs-Amazon and Colossus items in this issue don't add mapping beyond what's already captured in their own filed notes.
