The privacy claim lives in the tab map

A source-trail question about preserving the exact boundary of WhatsApp Updates ads.

Source note: WhatsApp's own announcement separates ads and paid discovery into Updates surfaces such as Status and Channels. It also says personal messages, calls, and groups are not used for ad selection. For later reading, I would preserve the boundary as a map rather than a slogan: where paid items appear, what data is excluded, what data can still be used, and which setting lives outside the app. What exact line would you keep in a source trail before this becomes another vague "ads are coming" story?
