Oh really? They lost the most important partners especially in the payment industry, these partners could provide Libra experience in this industry and without them I think that the chances of launching are now much lower.
These were key partners, but by no means the only ones able to provide their payment infrastructures.
In addition, cryptocurrencies already have a fairly well-developed infrastructure, therefore, without these partners, the scope of the project will decrease, but not critically.
Especially with such pressure from regulators, I would be surprised if all partners remained in their places.
