I don't think that was intended from the beginning (maybe I'm just  
too naive), but yes that's how things happened for PortAuthority. The  
guy appeared one day on the (then) DarwinPorts mailing list, telling  
he was intending to use Tk/Aqua to resurrect the (then) sleepy GUI  
for DarwinPorts, called DarwinPorts Manager IIRC, and got list  
members to provide ideas for his projects, test beta versions, even  
contribute code fragments or clarifications on the inner working of  
DarwinPorts. There were many iterations, 0.1, 0.2, etc., with name  
changes from TkDarwinPorts to PortBase and PortView to DPGUI to  

But then suddenly came the final version, 1.0, released as shareware.  
The argument, I think, was that the Aqua interface took more efforts  
than originally planned; accordingly, an X11 version was also  
provided, which was free and had not required these efforts. But then  
with version 1.1 the X11 version was discontinued, and the license  
was moved from GPL to shareware.

I don't know whether things happened the same way for Fink and  
Phyncronicity. But the fact that the guy feels the need to provide an  
explanation on his blog for his business practices would incline me  
to think they did.
