It depends on what Facebook has in mind. If they want to use Libra as virtual currency (which they will since it is meant to be a stable coin), then it is more likely that way around.
So much news on this project and it seems to me that he will not enter the cryptocurrency market for at least 2 years. All this is so far within the discussion.
I am sure that things will be quiet soon. I expect that the concerns and conversation will be revived when LIBRA is actually launched.
