In the almost weekly tradition of Facebook talking about something embarrassing they did on a Friday, the company is now fessing up to the fact that thousands of their next-gen virtual reality headset controllers have “easter-egg” messages inscribed on internal components that weren’t meant to be on non-prototype editions.

“Tens of thousands” of unreleased consumer units have the phrases “This Space For Rent” and “The Masons Were Here.” written while some of the developer units have “Hi iFixit! We See You!” and, perhaps most embarrassing, “Big Brother Is Watching” inscribed internally.
