Yours is a terminal mode app, mine is a host mode app. Lets do some one on one comparisions.
OK
Modes: DD: CW, packet, RTTY, SSTV, ASCII, FEC, SIAM, ARQ and FEC Pactor and Amtor, MT63, PSK-31/63/125.
WW: CW, Phone, RTTY, PSK-31/63/125
The user can create macros in WinWarbler that switch the PK232 into ASCII or Pactor or Amtor modes and support operation in those modes.
Host mode: DD: Yes
WW: NO
Agreed.
Access to CMD: Prompt when xmitting: DD:Yes
WW:NO
Agreed.
Can do soundcard RTTY and PK-232 RTTY at the same time: DD: NO
WW: Yes
Agreed.
Can run one TNC for Packet and another for digital modes at the same time: DD: Yes
WW: No
SpotCollector, which is also free, supports a Packet TNC.
Has waterfall for RTTY and others modes: DD: Yes
WW:Yes
Agreed.
Built in logbook: DD: Yes
WW:yes
WinWarbler also logs directly to the free
DXKeeper, which provides award tracking, QSL printing, and LotW/eQSL synchronization as well as powerful QSO capture and log maintenance capabilities. Would you like to compare your application's logging capabilities with DXKeeper's one-on-one?
Radio Control DD: Yes
WW: Requires another program
Yes, WinWarbler automatically interoperates with the free
Commander; would you like to compare your application's transceiver control capabilities with Commander's one-on-one?
Cost: DD: $99.95 new, $79.95 competitive upgrade, $49.95 upgrade
WW: Free
Agreed.
Support: DD: Phone, web, email
WW: Web, email
Defects reported in DXLab applications are corrected within 24 hours; given the diagnostics built in to each DXLab application, accomplishing this has never required a phone call, but I have on occasion called new users to answer their questions in real time.
As we've discussed before, you have a nice retirement from your days at Rose and IBM. I'm 50 and have 17 more years to retire.

I first released the DXLab Suite in 2000 while I was still leading the Product Group at Rational, and I'm not all that retired. I am a fervent capitalist, and have no problem whatsoever with you or anyone else charging for amateur radio applications. One of DXLab's objectives was (and is) to raise the bar for functionality and quality in amateur radio software -- at all price points.
