It's not the headset that causes the nausea, it's the software.
It's like blaming the plate for overeating.
To use a food analogy: You sell pizza, it is the best pizza in town, but the delivery driver sucks and food is constantly arriving cold or smashed. Your patrons aren't going to care that you always blame the delivery driver for the problems, or that the pizza COULD be good if not ruined, they're going to either shop somewhere else or quit buying delivered pizza. Same thing here, regardless who ruined the thing, the experience is still the same.
I absolutely would not blame the restaurant if my GrubHub delivery guy ruined the order.
And regardless, what the mythical "average consumer" does or doesn't do is immaterial. You should know better.
I don't know if "blame" is the right word, but eating off a large plate does make you more prone to overeating.
