I worked at Facebook when the Libra thing happened, and it was obviously meant to be a global bank that evades banking regulations by sprinkling crypto magic.
When it launched, employees were told that we'd soon be able to receive a portion of our salaries in Libra. Every practical feature of the system was effectively a Facebook bank account where the unit of currency was tied to a basket of major currencies. The rest was smoke and mirrors.
So yeah, Zuck feigning surprise about being dragged in front of CFPB was just an act (like most of what he does in public).
