Looks like Steam has similar conditions: http://store.steampowered.com/subscriber_agreement/

“YOU AND VALVE AGREE TO RESOLVE ALL DISPUTES AND CLAIMS BETWEEN US IN INDIVIDUAL BINDING ARBITRATION.”

“You grant Valve and its affiliates the worldwide, non-exclusive, right to use, reproduce, modify, create derivative works from, distribute, transmit, transcode, translate, broadcast, and otherwise communicate, and publicly display and publicly perform, your User Generated Content, and derivative works of your User Generated Content, in connection with the operation and promotion of the Steam site.”

One key difference is which services this applies to.

Steam: “in connection with the operation and promotion of the Steam site”

Oculus: “in connection with the Services”. Where services are defined as “use of physical goods, platform services, software, websites, applications, and content”
