The result is still 50/50, as the situation of libra right now, it will be hard for them to make another step. If they somehow manage to create an alternative plan on this kind of situation they may be able to stand even if their partners drop out on their partnership, and even government can't stop them from making a progress. Further announcement should be release soon for this matter and if it is positive for the side of Libra, this may help for them to make a new action plan.
Those probabilities are too high, you must understand that if Facebook decides to go forward with their project despite the protests of the governments there are going to be huge consequences, and if you are the CEO of Facebook you are not going to want to risk the company to those consequences, this is why bitcoin is a decentralized currency, because even if governments can try to influence some of the big players in this market they cannot stop bitcoin.
For example if they could scare away miners this will only mean that the average person will be able to mine bitcoin once again but in the case of Libra there is only one entity that they need to regulate and that is Facebook.
