Most likely management have deemed the product to not be making enough money (or instrumental in making money) for it to be included in corporate strategy. Also, the developers have probably tired of it so won't continue it in their free time. Be grateful it is open-source!
I don't know that it was a money issue. I feel like many of their products don't have a business model, per se. I just feel like it wasn't important enough to have developer cycles spent on it.
