Oculus co-founder, Nate Mitchell, announced the public via Twitter about the upcoming Oculus devices issue on Thursday. Tens of thousands of Oculus Touch controllers have shipped with weird privacy-related Easter Egg messages stored on their internal hardware.

These messages got onto the internal hardware of the Oculus Touch VR controllers, with final production hardware revealing ‘This Space For Rent’ and ‘The Masons Were Here’. Some dev packages were delivered, which were non-consumer units, and contained the sayings ‘Big Brother is Watching’ and ‘Hi iFixit! We See You!’

Nate Mitchell wrote the issue on Twitter. “Unfortunately, some ‘easter egg’ labels meant for prototypes accidentally made it onto the internal hardware for tens of thousands of Touch controllers,” Mitchell mentioned on Twitter. “But those were limited to non-consumer units. While I appreciate easter eggs, these were inappropriate and should have been removed.”

Unfortunately, it looks like Oculus recognized the easter eggs had been included in the consumer hardware before it could get rid of them. While the issue has been announced, no devices with the messages have been purchased yet.

The company is preparing for the releases of two new VR products, the standalone Oculus Quest VR system and Oculus Rift S. The devicess will both share the same Touch controllers that this issue affects.

While the majority of consumers of the Touch controller will never find the hidden messages, it’s an embarrassing blunder for Facebook. For more than a decade, Facebook has faced continual criticism on privacy issues.
