Facebook and Google didn't announce any harm from the GDPR. There are many companies that announce lower earning expectations from a simple 5 line App Store change by Apple and a one time popup asking you whether you want to be tracked.
FAANG aren't who I am thinking of here - much worse are the background check and risk reporting companies such as WorldCheck that maintain dossiers on you that can often be not much more than speculative fanfiction, which banks use to assess risk.
