If they left the project that doesn't mean they will not come back when Libra will be successfully launch.
Maybe they are just playing safe at the moment as Libra has been criticized by the government but since its not operational yet, its not a big deal though.
The influence of Libra is huge what they need to focus on is just to have a successful launch and good news will follow.
That's also what I'm looking for, these companies that left Libra will go back when it is safe, they have an interest to protect and they want nothing to do with Libra coin now, but things will change after they soften these adversaries, but everything is yet to be seen, so we have something to watch out for next year.
