oh, pshaw!
cracking msn and so on, can only help spread the word about how insecure it is! if a system can be cracked all the time, less people will use it! i certainly won't be helping any would be crackers, they can do their own research, but once they have, then fair enough! of course by that stage they won't be asking us for help.
No, if a network (such as msn) cannot deal with its own crackers without us (the Microsoft eradication society, after all) discouraging people from even trying to crack into it, then they deserve to fail on all fronts.
Cracking software just to save yourself some money is another thing again though...
