No it is not Copyright Infringement (Piracy is ONLY on the high seas where the Pirates have no country to call home) to have to crack a piece of data you legitimately bought in order to use it.
Sure, the company can ***** about it in their EULA (which isn't always legally enforceable anyway, look at Microsoft's attempt to lock every copy of Windows to a single hardware setup which is illegal under most countries Consumer Laws, such as in Australia where Microsoft Windows is recognised as a separate item to the hardware one installs it on), but YOU bought that piece of software for YOUR use, and if YOU want to modify it in order to get full use out of it (such as a No-CD crack) then I have no problems with it.
WAY back in the day with Diablo II (around Version 1.03 or 1.04), there was a NoCD crack floating around the net that allowed one to play the game without the CD in the optical drive if one wished. In a later patch (around 1.09 I think it was) Blizzard officially put their own NoCD crack in the game so player who used that patch didn't have to finagle with a dodgy site in order to save their CD's from wear-and-tear.
