Although Sony is notoriously known for being anti-hacking, modding, or anything of that sort, Sony CEO Jack Tretton is apparently okay with this sort of thing. At least, he stated this in an 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 this statement will change some of Sony’s position regarding this sort of thing, but realistically, probably not.
