I'm the maintainer of FracturedJson. The decision to stop publishing a binary for the CLI version was made a long time ago: fewer features, fewer users, less mature .NET tooling (as far as I knew). And as you say, .NET isn't a common language for distributing CLI tools.

I plan to take a new look at that when I have the time. But a port to a more CLI-friendly platform could probably do a better job.
