Sony previously avoided the war entirely. Having Other OS kept a great deal of hackers at bay. The problem was a few too many restrictions and tinkers who wanted more power. They would have left the security intact had the system not been crippled from the OtherOS.
Sony should have left well enough alone, fixed the hole, allowed access that people were looking for, and retained Other OS. The war would have quickly fizzled.
As it is now my family gripes every time the thing requires an update to connect and I'm ready to abandon the PS3 completely. I still have a 10GB partition with Linux that I can't use.
