Where was the FTC action when it was revealed that period apps were selling user data?

It was here -> https://www.ftc.gov/legal-library/browse/cases-proceedings/192-3133-flo-health-inc

And here -> https://www.ftc.gov/news-events/news/press-releases/2021/06/ftc-finalizes-order-flo-health-fertility-tracking-app-shared-sensitive-health-data-facebook-google

I know you're being rhetorical, but your post could easily leave people with the impression that the FTC did NOT go after those apps too, when ofc they did. There were financial settlements, there were requirements to obtain affirmative consent, there were prohibitions on prior behaviors.
