If you need context:
Oculus has been offering funds to VR devs in exchange for limited time exclusivity to the Oculus Store. This wouldn't be such a stink if the news didn't immediately follow Oculus Store DRM adding checks for the Oculus headset hardware. So, a game bought through Steam can play on either a Vive or a Rift depending on support put in by the dev. But, a game bought on the Oculus Store is blocked from running on a Vive.
IMHO, the conversation about this topic is very muddied between the four issues of funding, store exclusivity, DRM and hardware blocking. But, AFAICT, the PC gaming openness advocates are clearly OK with Steam DRM and mostly fine with funded, temporary store exclusivity. However, the hardware block is a serious issue. (At least in it's intent. In practice, it was immediately worked around.)
