I'm afraid I agree with several others here.  Attitude has a lot to do with it.

As Drew pointed out, there are some issues in favour of FM sats, most notably
portable operation.  Until recently, portable SSB operation meant not only a
pair of transportable rigs or a FT100 or IC706 style rig and an outboard
battery (now, the FT817 could be pressed into service), and that's before
considering the implications of Doppler shift (which usually means that 2
portable boxes for full duplex, or rig like an 847, or taking the lappy along
for computer control).

Hardly practical for casual or opportunistic use, often not practical for
emergency use and certainly less likely in less affluent countries.

Doesn't stop the opportunistic "bundling" of a bent pipe in a packet satellite.
Afterall, look how that sort of packaging has extrended UO-14's useful service
life.

SO-35 also demonstrated that FM and packet can time share and take turns.
