Dave,
I guess the implication I was trying to make was that people assume there 
is little or no support with an open source or free application.  
You said shareware, not "free" or "open source".  They don't mean the 
same thing!
shareware = software distributed from person to person that you
            can try, but are expected to pay for.  source code
            is not typically included.
freeware  = like shareware, but you don't have to pay. source
            is not typically included.
public domain = software given away for free with no support, etc.
                source code is included, and it's yours to do with
                as you wish, no strings attached.
open source = software is given away for free. support is provided
                by the community, often informally.  source code is
                included, and you are allowed to make changes and
                redistribute it, provided the original author is
                given due credit.  Sometimes restrictions are added
                requiring your distributions to include source code,
                and/or only distribute with other open source software.
                Advocates say that open source protects your freedom,
                because if the original author drops support, the
                community has both the source code, and the legal right
                to change and redistribute it. (And thus you can now
                support it yourself.)  So you aren't at the mercy of
                the original provider.
