Back in the days of Atari ST and Apple IIe computers, piracy was not as big a concern, and games from computer giants like Electronic Arts and Maxis (SimCity) were not copy protected, and they made a lot of money.

Now, 20 years later, these publishers prevent you from using the game you purchase without adhering to strict set of policies determined by the publisher (and because of DRM, these games will not work if the DRM servers that support these games go down.)
Considering the hoopla over Spore, it occurs to me (not that I have the programming experience to pull it off) that if some trojan/virii genius could pull off a mass infection to turn multiple computers in to zombies, that pointing those zombies at Spore’s DRM servers in a DDoS attack, that would be the best way to show all of the loyal consumers (like myself) who paid cash money for Spore just how unstable EA’s commitment to providing a game really is.
DDoS the DRM servers and no consumer could authenticate.

Have you seen the snarky Stolen Pixels comic about EA’s tremendous learning curve on DRM? Their amazing solution to everyone’s complaint is to keep everything the same… but next time, they’ll allow five installs instead of three!
