I don't know if you are including me here, but I very much was following the Oculus since its inception, and I'd never downplay Camack's contributions.This post is right on point and I'm surprised by how clueless lots of opinions are in this thread. Carmack giving his support, and showcasing the kit with a custom version of Doom _is_ a huge deal and was one of the reason why the Oculus got some much tracktion in the early days. People who are downplaying this werent following this when it came about.
I just disagree in the strongest possible terms with the idea that a company "owns" whatever its employees decide to do in their spare time.
