oh come now...
microsoft might as well put up a big-ass sign on their front lawn (and their lawn is huge) that reads: hackers beware!..
and if they ever catch these vigilantes they can mount their heads on shish kebab skewers and offer them at their next power luncheon....
(... ewww, totally makes me picture klingons devouring meat and blood..)

this whole stunt just reeks of bully-ism...
and keeps supporting the image that they'd rather shell out half a million than actually fix the problems..
they are all too aware of the flaws, but they choose to ignore them so they can sell it in their next upgrade or version at prices that make buying a whole new system with windows pre-installed more cost effective...

c'mon... the fact that u avoid fixing software issues... not because u can't, but for money, only fuels the fire for these virus artists.....
so don't blame them... blame ur greed for the green...
