Sony hits snag in PS3 hacking case

Click on this link to read a Washington Post (1-18-11) article about how Sony is having difficulty suing a hacker for hacking into the PS3 game console (and then publishing how to do it).  Should owners of technology have the right to hack them any way they wish?  Is this a separate issue from that of sharing how to do it with others?  Or, if I have the right to hack my PS3, why is it wrong to tell you how to do it, if you have the same right?  Are content mediators that carry the instructions liable for doing so (as Sony apparently believes)?
