Yeah, the evidence they cite for VR declining seems to be entirely within the space of 3DoF VR, like Google's Daydream and VR video:

> Many big name adopters have abandoned their VR projects. Google recently halted sales of Daydream, its VR headset, admitting that "there just hasn't been the broad consumer or developer adoption we had hoped".

> Meanwhile, the BBC has announced it is ending the funding for its VR hub, less than two years after it was founded.

6DoF VR with tracked controllers (Quest, Valve Index) is a whole different beast, and actually seems to be gaining momentum lately.
