When I read that and I think Sony BMG's rootkit or SecuROM. Or maybe just examining the security implications of a game install without letting the manufacturer know about it by bypassing a phone-home feature. Actually, ArsTechnica has a good article up about this too: http://arstechnica.com/tech-policy/news/2010/07/apple-loses-big-in-drm-ruling-jailbreaks-are-fair-use.ars http://arstechnica.com/tech-policy/news/2010/07/apple-loses-... They specifically mention this clause: It turns out that the real target here is the DRM itself, specifically two controversial systems called SecuROM and SafeDisc. Professor Alex Halderman, a longtime security researcher in this area, begged the Library to let him investigate these kinds of invasive DRM without legal worries.
