Now, as for ethics.
While ethics is relative and should be completely absent from such scenarios, I'll humor you. You believe it is unethical for Sony to have removed a feature. They removed the feature to protect the console and content, along with other players. It was a hacker's loophole.
Now, for the "protection from piracy" part. This I'm not entirely sure about. I've never seen any concrete evidence anywhere that the feature could indeed be used to crack the system - it sounds more like high-ups who are more concerned with profit than the technical side of things overreacting.
|So, the "ethics" sets in. Remove a feature a small fraction of people specifically bought the console for, in return saving countless of resources of inevitable exploits and protecting the integrity of development and network play. Or, keep the feature and satisfy the small fraction, and risk having exploit after exploit, damaging the community and integrity of the system. Logically, it makes more sense to satisfy the larger community and protect the original, main function of the console.|
|At this point in time however, it is ironic. Though at the particular time when the decision was made, the more ethical choice was picked. It comes down to, you can't have your cake and eat it too. Not to mention... This "ethics" thing doesn't fly with this situation. According to Geo, this is an eye for an eye scenario.|
|Are you saying it is ethical to crack a closed source system and publicly spreading it knowing it will cause monetary damage?|
|Now, personally I believe this otherOS thing is a complete BS scapegoat. The kid is arrogant and greedy, I have theories of his real reasoning, but I'm not buying that he did it for otherOS.|
Also, a note: I don't know everything. I will always reconsider my stance on an issue when they're challenged with solid facts and irrefutable evidence. At the moment, though, I'm simply not convinced that the threat was anywhere near great enough to warrant removal of a feature, however small the number of people actually making use of it.
LAST ADDENDUM TO MY WALL OF TEXT:
I do believe that, regardless of the scenario, considering subjective matters as well is very important and that ethical considerations are no less important than what the book of law says.
