The project name, its community center and hosting environment, the active participation and consent of the copyright holders of the software was withdrawn. This is a dead project, we can all see it. If you want to use it and contribute and get help, you have no where to go.
"It's still open source because you can fork it if you really want" is a specious and unhelpful attitude, and it tells me that you, like the owners of this thing, are not to be trusted to manage such a thing.
The project is Apache2 licensed. You can literally do anything you want with the code. Stop trying to push guilt on people for no longer providing free services.
I suppose you can ask them for a refund.
the only reason to ever fork a project in earnest is because the original project owners are not willing or able to cooperate or accept patches. in other words you fork because you have nowhere else to go. exactly the situation we have here.
