What the models said for it

Verbatim evidence the judge attached to positive labels.

No positive label carried a quote.

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Trade-off: service-heavy, slow (quarterly or semi-annual refreshes), six-figure engagements” Claude Opus 5 · Attribution & MMM · comparative prompt · soft negative

“legacy enterprise vendors (e.g., older service models from Nielsen, Kantar, or Neustar)” Gemini 3.1 Pro · Attribution & MMM · negative prompt · soft negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page gets a verified contact who is told when each edition publishes; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Kantar, applied by version and listed in the change log; and a logo and one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or quadrants, any preview, or any say over which quotes appear. Sponsorship is separate: a sponsor funds categories or buyer dimensions and is named on what it funded, and the rules are the same for every sponsor.
