Really? Zuckerberg giving up? Maybe he just introduced this to test the viability of payment system but later on, he will be more ready than ever. I don't think he will easily give up on Libra as everyone is already integrating blockchain technology within their system.
He will not give up, and things are not working according to his way, so he might take time to launch the Libra payment system. Sometimes we have to face the tough situation and surely we are going to see the Facebook future payment system through Libra. Now governments are also not supporting the Zuckerberg to launch the Libra coin.
