quite the opposite actually. Think about it, it's been 3 years since the first of this new generation of VR started. I've followed it very closely and own a couple of the devkit headsets that have come out over those three years. I have watched it evolve from a barf inducing curiosity to an established and amazing new format. 99% of the work that has gone into it is finding out what you can and can't do in VR. Some people are nearly immune to the motion sickness (John Carmack, Oculus CTO) others are highly susceptible to it (Brendan Iribe, Oculus CEO) At their last keynote they talked about how excited they were that Brendan was in a new Mincraft project for well over an hour and was still having a great time, where up until that time he was 15 minutes and turning green.
It's really hard to sell a product when a good review is usually followed with "5 stars! It didn't make me sick." Oculus has developed the best practices around what makes a headset get that kind of rating.
