So 10's of thousands, maybe even 100's of thousands of people had working inks in their printers, then HP pushed their way into those printers and did something, and now those people don't have their ink anymore. You might argue that HP was "allowed" into those printers by some EULA agreement so that makes it somehow better, but if the cable guy whom you allowed into your house tried to walk out with your TV you might call it stealing... If they're seriously allowed to do this, how is that different from just ordering all of the printers to dump their inks into the spill tray whenever they need a revenue bump? So "remember that time when HP hacked all those printers and stole everyones ink?" seems about right to me.
