7D files are no different from other files from same sensor (60 D, t2i, t3i, etc). its an 18mp 1.6 crop sensor which many times used for wildlife photography, with long lenses, which are further cropped. some of this "special" needed processing is the sensor, part of it is the subject matter.
As a very high density sensor, it is extremely demanding not only on the lens, but also on technique. viewed at 100% it requires more sharpening than for example a 5d2 file, or even a 1d4 file. At the same time, you have to be more careful with noise compared the the other two cameras mentioned. add to that many are shooting picture of moving objects at 400mm, and then cropping a bunch too, and shooting at 1/800 second, and not getting sharp results, and they are wondering why.
But to go back to you original question, viewed at 100%, they need more aggressive selective sharpening and noise reduction.
