there have always been a subset of vr headsets where the displays and optics are good but are otherwise flawed, that have been relegated to the flight sim and sim racing world lol

(I have a reverb g2 and use it for 'normal' vr games, but I understand its most popular among sim people, I think Pimax headsets generally see similar use)

(also apple has told no one about ALVR and other streaming, the basically only people who will know about it are the people who liked and were using VR already and probably already have a headset they are generally satisfied with, so I doubt it has significantly affected their sales, they still shot themselves in the foot by pretending that Fruit Ninja or whatever was the only game that people would want to play with their headset)
