That reason isn't really that important, I was just mentioning and trying to explain it. The overall reasons were given here >>273808437

>Oculus wants you to install THEIR drm in order to play exclusives BUT FUCK STEAM FOR WANTING TO INSTALL DRM TO PLAY LITERALLY EVERYTHING ELSE
Well, yes, that's kind of what they want to do, and Steam wants you to not install or use Oculus software if they could have you do that. Since almost all games support SteamVR anyway, and most headsets work on SteamVR (without too much hassle), they don't need to take any actions. On the other hand, Oculus, in order to be successful, needs to at least have users stay on their store and buy things there as much as possible. Hardware exclusives don't make sense for their business, and their employees, even after Palmer left, have expressed that they'd like to eventually support the Vive, but the way the APIs have been developing so far has made them strategically decide to hold off on publishing SteamVR builds of games, and to wait for OpenXR.
