Don't count on it. This is definitely not the case for their other product the Gear VR. You can use nothing with it that hasn't been approved. The device is locked to their Oculus Store app and only that app. It is a completely walled garden and there is little reason to think the Rift's Oculus Home app will be any different. Facebook considers total control of content for this to be of the utmost importance and they own Oculus. Just a small comment for those of us who were still holding up any kind of hope for 'side-loading' apps that were not in Facebooks app store. And a friendly reminder, Oculus HAS dropped support for Mac and Linux. They've said it's just for now, but we all know that doesn't bode well for openness in any way."Of course, this only applies to apps available through Oculus’ official app store. There will likely be unofficial app stores where users will be able to download whatever they want."
