"As some of you suspected the sudden extreme jump in the pledge amount is indeed by Palmer Luckey," Revive developer Jules Blok said in the campaign's blog. "I'd like to thank him for his pledge and everything he has done for the VR community as a whole."
Revive was a response to Facebook's exclusive Oculus titles, which only worked with the Rift headset and were available through the Oculus Store. Before that, the VR community had hoped that games would work across the Rift and Vive, so as not to stifle innovation in the VR arena. While it makes sense for gamers to be upset, it's also worth considering that Oculus funded plenty of titles that wouldn't have existed otherwise. So it's not surprising that Facebook would want to keep those games to itself.
Facebook initially pushed back against Revive by implementing a headset check, but it didn't take too long for the app's developers to crack Oculus' DRM. The social network later relented and removed its headset check, which led Revive's developers to remove its DRM cracking.
Now, Vive owners can easily play Oculus titles using Revive. It makes sense for Facebook to avoid causing too much of a fuss, since they still have to buy the games from its storefront. While Luckey's support is a bit surprising, given that he was the public face of Oculus for years, it's in line with his personal philosophy of keeping the VR ecosystem open. And, if anything, it'll certainly be more well received than his plans for a "virtual" border wall.
