Getting tired of having to write it over and over again while ignorant people keep repeating the myth that by taking away the 'Other OS' option Sony is preventing any PS3 hacks. That is Sony-propaganda, and complete and utter nonsense. Removing Linux at this point won't stop anything. The genie is out of the bottle. Furthermore, Linux won't be needed to exploit any security holes once they are found. Fact.
All Sony achived by this panic reaction is to make the wrong crowd angry (so far you could run your own programs on PS3, now you can't), which means we'll see a useful hack rather sooner than later. Sony effectively shot themsleves in the foot. Deal with it.
