I think Facebook (and maybe MZ in particular) was hubristic from the start. They have a deep trust deficit and they just don't (or don't want to) realise it. If Libra was from anyone other than Facebook, or if it was from a proper AND neutral (ie. not dominated by Facebook) consortium of tech companies and organisations, it might have had a better chance.
