The exact change

Before

Fabricated Werner Vogels quote about Lambda being AWS default compute. Unsourced named-companies Lambda usage claim including a suspiciously specific iRobot Roomba fleet detail. Fabricated iRobot-specific authorizer-caching claim. Capital One idempotency claim attributed to a fake source ("publicly documented in open-source idempotency libraries"). Tim Wagner quote about VPC-attached Lambda misconfigurations, unverifiable despite his real title/background.

After

De-attributed the Werner Vogels quote to plain prose. Softened the named-companies Lambda usage claim (Netflix/Capital One/Coca-Cola/iRobot) to a general enterprise framing. Generalized the iRobot-specific authorizer-caching claim to a general statement about high-throughput IoT/telemetry pipelines. Generalized the Capital One idempotency claim to reference the pattern as widely documented in open-source idempotency libraries generally, without the fake specific-source attribution. De-attributed the Tim Wagner quote about VPC-attached Lambda misconfigurations to plain prose. Verified and kept the accurate 10 trillion invocations/month by 2024 statistic unchanged.

Suggested change

Verified and kept the accurate 10T/month Lambda statistic. De-attributed/generalized 4 fabricated specific-company claims (Netflix/Capital One/Coca-Cola/iRobot, Capital One idempotency libraries, iRobot authorizer caching, Tim Wagner's specific claim) and a second fabricated Werner Vogels quote.

Why this is better

Applied fact-check fix: de-attributed 2 fabricated quotes (Vogels, Wagner), generalized 3 unverifiable named-company/specific-source claims, kept the verified accurate Lambda invocation statistic.
