I haven't used one of those, but I can guess what he means based on owning an Oculus Rift 2. Let's say I want to start playing a Steam game with my headset. To do so, I must install the Oculus software, sign in with my Facebook account (it's a brick with a headstrap without an account), then find the setting that enables "non-Oculus software" to operate the Rift display. Using the Rift always starts the Oculus software. There are shortcuts on the headset that throw you into Oculus's own environment for buying and launching games.
