Libra is not all that bad. While there are problems with Facebook gaining yet another source for information that takes advantage of privacy terms, I think a stablecoin by GAFA is in the right direction. It speeds up the adoption of cryptocurrency by a lot.
Paypal and other "digital cash" solutions are fully centralized which makes it impossible for devs to build on top of their platform. This means that problems that arise cannot be solved by devs looking at the problem from the outside.
Libra gets around this by having an open platform that anyone can build on. Anyone can create a Libra wallet, and anyone can build Libra services. If we have a big privacy problem with Libra in the future, we might be able to find a way around it. Libra supports scripting on-chain which would make atomic swaps possible. If something like atomic swaps are possible, can we hide information from Facebook et al? Or what about mixing Libra on-chain?
