I doubt this is the case.  The military is unlikely to share a data 
stream with lowly commercial types when they clearly work so hard to 
keep it military only.

All the documents I can find refer to civilian (L1) and military (l2) 
bands.  There is no distinction made between general public and 
commercial use.  Even the FAA does not use the military signal, after all.
