Understandable. But i like privacy and the whole thought behind FOSS. I am a Software developers myself and like to dig into code and See for myself how it works and play with it.
Since the release of Oculus Dev Kit 1 (de.m.wikipedia.org/wiki/Oculus_Rift) 10 years passed. So i thought that could be a long enough time for an OpenSource-Community to drop a Kind-of-alternative to properitary Oculus Software.
