With the flurry of hacks surrounding the Apple TV, including the ability to run a full version of Mac OS X, there's been some concern and unfounded speculation that Apple may be specifically disabling these hacks.
The most official word available comes from Engadget with a report that Apple has let them know that they are not actively involved in shutting down hacked Apple TVs.
Apple's stance, it claims, is more along the lines of: it's your box, do with it what you please -- but be mindful of voiding that warranty.
