I think things are gradually changing.  A LOT of print shops, whether MAC or
PC-based, are using a gamma of 2.2 now.  It has/is become a defacto
standard.  Probably just to keep all things level.

Guessing now, most shops were MAC based, most input was getting to be from
PC, so it all evened out for continuity.
