First off, very sorry that you are angered by our decisions. I did say that OpenNI is put on hold, not dead. We have been focused on many other features, including releasing Cinema Director, and OpenNI is not a priority since the Primesense acquisition.
You are correct about the documentation. This will be updated ASAP, and thank you for pointing this out.
As for continued OpenNI development. We are aware that it is not dead and that it's open source and in the hands of a capable community. However, when running a business, we need to prioritize our development efforts, and add/enhance features. Now that Cinema Director is released we are looking at enhancing Mo Cap. We will look at revisiting OpenNI with the link you provided as well.
Finally, we have no issues at all supplying you a refund of Cinema Mo Cap. Please email us - email@example.com
and I will arrange a refund through Unity.
