"Normal people" may not care, but enough of us early adopters / tech savvy people do care to have
some impact here. Facebook's reputation is so deep in the gutter that some people will never purchase anything from them (I count myself among those ranks).
VR's widespread adoption has been "right around the corner" for at least a decade now, but it keeps failing to actually materialize. These things are niche gaming peripherals still, and proponents can ill afford to ignore potential users if they really want to reach ubiquity.
