Of course reality contradicts this theory.

To get a start toward understanding how this could possibly be the case, 
read http://perens.com/works/articles/Economic.html
especially the part on "Enabling Technology vs. Business 
Differentiation". This will explain what parts of a program a business 
must keep proprietary, and what parts it can share.
Then read 
http://itmanagement.earthweb.com/osrc/article.php/3801396/Bruce-Perens-Combining-GPL-and-Proprietary-Software.htm
on how to combine GPL and proprietary software, to see how businesses 
can work with the GPL and keep what needs to be proprietary separate 
from the GPL.
Then read 
http://itmanagement.earthweb.com/osrc/article.php/12068_3803101_1/Bruce-Perens-How-Many-Open-Source-Licenses-Do-You-Need.htm
especially the part about when a business might want to use the GPL.

    Thanks

    Bruce
