It is a stable coin with a consortium of big companies as the validator. If Libra reserves genuinely backed by a 1:1 ratio, then I don't see any serious problem. However, If they use the fractional reserve, I'm afraid inflation will speed up rapidly and take down the global economy (assumed Libra would become mainstream). Perhaps this situation is good for Bitcoin. People will realize that Bitcoin is the only non-debased currency.
Rather, we should be concerned about which companies are part of the consortium. It might also give a good idea for the future and explain what the OP wants to mean. I can guess already these companies. The same Zionist enterprises interested to rule the world on behalf of a few people.
A type of company like Facebook isn't designed for finance activity, it's my opinion. And I doubt it will be a success, FB has lost his credibility long ago
