is this the incident where Apple pulled Meta's developer licenses or is this a new breach?

IIRC, Apple pulled Facebook's enterprise developer cert over Onavo stuff; again IIRC, Apple had pulled Onavo from the app store, and Facebook continued to offer it to users by enrolling them in the enterprise developer system; on January 30, 2019 Apple revoked that cert: Onavo distribution was stopped in addition to Facebook's internal apps.

This article says it's about Apple’s App Tracking Transparency (ATT), introduced in 2021. Facebook changed their name to Meta in 2021 as well.
