What he meant was FM birds.  Not just "APRS" birds.
The resason not to  put out the SSB birds is because 
of the point of deminishing returns.
- This is an APRS service for APRS mobiles
- Fixed stations with PC's dont need it as they can run
  any kind of satellite tracking program
- 99% or more of the mobiles only have FM
- Most all of the non FM birds require gain antennas

So serving the FM birds serves 100% of the APRS
mobiles that are interested.  Doubling the channel
loading to serve also the SSB birds that can only be
used by 1% of the mobiles seems like QRM to the
other 99%.

Or something like that...
