People that don't care if their web server/desktop machine/refrigerator get hacked are the cause of much grief to other Internet users. If one doesn't recognize this and build in security accordingly, one's OS will continue to be hacked regularly costing businesses millions of dollars in lost time and pissing off those of us that think it's rude.
Personally, I'd like to see someone pull a Jay and Silent Bob routine on people that let their machines get infected. I know that the thought crossed through my mind while I was putting block rules in my firewall to stop 7,231 machines on my DSL provider's network alone from constantly querying my webserver day and night.
If someone went around to every Windows user that got infected with such worms with a baseball bat and reduced their machines to sparking junk, Microsoft would have a much smaller footprint in the market.
