Seems like Electronic Arts has slightly succumbed to the internet outrage over Spore's DRM and will relax the copy-protection on Will Wright's new game in an upcoming patch.
The patch will add functionality to de-authorize computers, much like iTunes works for purchased tracks. You will still only be able to activate the game on three machines at a time, but you will be able to manually remove computers from the list.
This means that users should avoid being locked out if they significantly upgrade their computers several times or purchase new machines.
We think this is an excellent compromise. There are still no plans to change their policy of one online-enabled account per CD-key, however. While this might not affect most users, it is an issue for households with multiple gamers.
