According to wikipedia:

"In digital photography, the raw file plays the role that photographic film plays in film photography. Raw files thus contain the full resolution (typically 12- or 14-bit) data as read out from each of the camera's image sensor pixels."

This would imply no noise reduction in the RAW file. Simply data from each photosensitive site. Covered with a RGB filter then light converted to electrical charge and quantified.

They all apply NR but not to this degree. It certainly seems to be worse with the X-E2 in my experience. It doesn't help that my wife has freckles...

It doesn't imply that at all. That data gets manipulated to the RAW file by Fuji, nobody will ever know for sure but most experts agree they add a decent amount of noise reduction to their raws.

Could you post a link to one of these experts, please? I would like to learn how they think this happens.

How would you think that is happening? A RAW file contains only data from each photosensitive site (RGB). Noise happens at the pixel level. Pixels are created by interpreting this data (Demosaicing).

Reading this might help: http://en.wikipedia.org/wiki/Demosaicing

If you want to learn, Google "cooking camera RAW files" or "Manufacturers manipulate RAW data" something along those lines. It may help you understand a bit better.
It's a bit of a con really, but you're not really to blame becasue it is insunuated that a raw file is purely camera data.

Manufacturers aren't stupid, they know people look to DPreview, DXO etc who compare RAW files against different manufacturers so tweaking them to produce less noise for example, is going to give them better test result and therefore better sales.
