Although Sony is notoriously known for being anti-hacking, modding, or anything remotely resembling that sort of thing, Sony CEO Jack Tretton is apparently now okay with it. At least, that is what he stated in this interview with The New York Times:

"No, there’s a real misnomer there, we embrace independent game development," he said, "If you call that hacking, then we embrace that. We give people tools that let them create new experiences. What I don’t think we are in support of is someone trying to hack our device to pirate software and possibly collapse the platform."

This is an odd statement, given that Sony regularly releases updates that disallow Playstation owners to use hacks or mods. Maybe Sony decided to change their official position regarding this sort of thing, or maybe Jack Tretton is personally okay with it regardless of Sony's official position, but this may have to do with backlash over the whole Playstation Network situation. For now, all we can do is speculate and see if this position is put into action, as actions generally (but not always) speak louder than words, given that words are written.
