and no one may duplicate it or distribute it without that
company’s permission.

use the proprietary software.

Corel Office X3
Windows 7

which provides the original source code used to create it so
that advanced users can modify it to make it work better for
them.
Examples:
Linux
GIMP
Blender
Inkscape
Mozilla Firefox 3.0
OpenOffice.org
KOffice
