Seems hypocritical of Notch after all his bitching about the Facebook Oculus acquisition.
Not at all really. Oculus Rift was a Kickstarter thing, i.e. publicly funded by fans. Mojang sold alpha access, but Minecraft was getting made and being sold at an early adopter discount. The crowd funding thing is what Notch got upset over because to him it seemed like a bait-n-switch.
