Optimaximal: Seriously people, do some research. Every single piece of software that comes with on-disc copy protection, be it any version of SafeDisc, SecuROM, StarForce, TAGES, FADE or LaserLok, installs drivers too your machine - it couldn't function without it.
Perhaos you should do some reseacrh as well. Indeed they install drivers. But not all of them have Ring0 access and not all of them leave the drivers on your system after you uninstall the software in which they were included.
Optimaximal: Do the math and YES, vote with your wallet, but don't reject DRM outright since its here too stay. You might as well just stop gaming all together.
It's only here to stay if people accept it. If you just throw up your hands and say "Well, it's here for good and it's not going to change" then that's exactly what will happen. If you fight it and refuse to buy products that use it, then you can be damned sure when a company sees it's affecting the bottom line that they'll drop it.
