It's difficult for me to parse what exactly your argument is. Facebook built a system to ingest third party data. Whether you feel that such technology should exist to ingest data and serve ads is, respectfully, completely irrelevant. Facebook requires any entity (e.g. the Flo app) to gather consent from their users to send user data into the ingestion pipeline per the terms of their SDK. The Flo app, in a phenomenally incompetent and negligent manner, not only sent unconsented data to Facebook, but sent -sensitive health data-. Facebook they did what Facebook does best, which is ingest this data _that Flo attested was not sensitive and collected with consent_ into their ads systems.
