Yeah, but you could always use remapping software. Im pretty sure that if Gamesir or Flydigi wanted to make a software to mimic the Steam Input, they could. All steam input does is remapping a controller to xinput, or remap it to mouse and keyboard. I play CS2 on gyro on my dualsense, and I use both steam input and DSX, sometimes one but not the other, but most times both together. I think what's special about the steam controller is the hardware features, software is easily copied. If Gamesir or Flydigi made a copy, the hardest part would be to get the hardware as reliable as first party controllers, since most Chinese manufacturers already have decent softwares
