I don't know if I've ever seen so many useful Open Source software products go proprietary at once; Vault, Consul, Terraform are all useful parts of many people's stacks, that they chose specifically because of their licence.
Hopefully they all get forked (or existing forks take off), and it is just a matter of the community converging on the winner that we all use in the future.
Not possible, at least for vault and terraform
The way the architecture works, any fork would have an impossible task to take off and maintain compatibility
