## Warned against

- Google Analytics 4: 6 of 14 labels negative. "Avoid using attribution reports alone as the final authority for cross-channel investment." (GPT-6 Astra, negative prompt)
- Adobe Marketo Measure: 8 of 14 labels negative. "Bizible became Marketo Measure under Adobe, and B2B practitioners have complained about slowed development post-acquisition." (Claude Opus 5, negative prompt)
- Google Meridian: 4 of 21 labels negative. "Meridian and Robyn are free and production-grade, but they require in-house econometrics and Python capability... At 500 people, buy, unless you already have econometricians." (Claude Opus 5, scale prompt)
- Meta Robyn: 6 of 16 labels negative. "Robyn’s documentation emphasizes analytical expertise, modeling assumptions, and experiment calibration. Neither framework removes the need for competent implementation." (GPT-6 Astra, negative prompt)
