The reason is not a secret.  The reason is that patents apply, and 
because freely available libraries are very slow or have arbitrary 
limitations.  I have some hopes for OpenJPEG since it is actively 
developed and clearly improving.

If you compare the compress/decompress times of a JPEG2000 library 
like Jasper to libjpeg, the difference is like night and day. 
Minutes vs seconds.

Regardless, JPEG2000 has been selected as the basis for digital cinema 
(DCI) so it is being used.
