emacs launches non-free netscape by default

[Olivier Esser]

Midle-clicking on the "emacs-gnu" logo image at the first sreen of 
GNU-emacs-21.3.1 to browse http://www.gnu.org as suggested by the 
tooltip lauch by default the function browse-url-netscape which is by 
default netscape.

Netscape in a non free program as you can see in the terms of the 
licence agreement of the current version of netscape as can be 
downloaded from their web site:

        NETSCAPE 7.1 END-USER LICENSE AGREEMENT
        Redistribution Or Rental Not Permitted
        [...]

They are free high quality web browsers available such as mozilla, 
konqueror, galeon, ... . Why is the default browser lauched by gnu emacs 
a non free program?

Sincerely,

Olivier Esser
