Metal Machine is also an EZX and is meant to be processed. Many people, including several forumites here, also asked for an SDX version with raw samples. The Avatar kit is quite raw sounding and God knows that when we hear it in examples, it's been processed. Even with S2.0's built in effects, i've yet to hear a stock preset that actually sounded good with any of their packs; clearly they're not using those in their clips.
I guess the issue here is that there isn't a distinction between raw (SDX) and processed (EZX) sample libraries, like Toontrack has. Still, when I buy a sample library, I fully intend for it to not sound like what it does in the manufacturer's examples, as it'd be dumb for the company to put the raw sample pack in with some guitars and bass and call it a day. Of course they're mixing them (if even just with a little EQ), to fit a mix...
