Sony has a terrible history with making their devices portable to other platforms.

VR was well established by the time they joined the party, especially by the time v2 came along. It was a decision to ignore integrating with PC protocols when designing their hardware and drivers.

Sadly, very predictable for Sony. They would rather have poorer sales than to open their devices to be used outside of their platform, and vice versa.

Nothing has stopped them from making their controllers compatible with PC besides refusal to pay a licensing fee to Microsoft, which must be trivial compared to the increased sales of their standard controllers. Hell, I bought a couple Xbox controllers just I could avoid fucking with 3rd party dual shock drivers every fucking time I tried using them on PC. And I much prefer the Playstation controllers.
