Shame on anyone who is upvoting. Libra is not a cryptocurrency, or a stable coin, or anything. It has nothing to do with the principles that started Bitcoin or Ethereum.
Some developer looked into Facebook’s new coin Libra code and opened a pull request addressing a critical security vulnerability that is - centralization of authority and decision-making power. The PR suggests fixing the centralization issue by replacing the whole project code with Bitcoin’s code. The PR got over a hundred comments and likes before getting closed by Libra.
Facebook's Libra is not a real crypto currency, it is Facebook-centralized and regulated tender.
