Well Libra has still many partners so I think they can still continue without those drop out partners. I think the government behind this why the big companies drop out partnership with Libra, who knows.
Libra is currently trying to create a negotiation with FINMA and this is the only way for libra to acquire a license payment system from swiss to operate in the Canadian countries. Government is only trying to protect its economic system. This is why EU and US have already banned libra and the authorities from EU and US not accept libra as the next payment system.
it still continues and libra is not yet giving up.
