Well Apples AAC encoding is also proprietary, so Sony is not exactly acting any different to Apple in this regard.
Sony have provided the ATRAC licences far more widely than Apple have the AAC licence. So far only Dell (who have since given up I belive) have created a AAC decoding player.

IMHO ATRAC is a superior compression technology, it is at least equal to AAC.
