Hackers that break into secured computers systems as a favor are exactly like cops that break into your house just to prove how easily a criminal could do it.
How considerate of them!
Maybe they will soon offer a similar service to break into my car and spray bleach on my lawn, just to prove how easily somebody who actually meant harm could do those things.
But the fact that they are doing it as a favor, to point out what truly anti-social behavior could look like, potentially, if the perp was all mean and stuff, that is supposed to make it all better.
Yes, truly the world would be a much better place if we had more people breaking laws and invading people’s privacy and property in order to lecture all of us on how lucky we are that real criminals are not doing exactly the same thing.
