What kind of idiot would invest 3 years in research without some kind
of plan as to how to pay for the research?

The implication that the GPL prevents you from creating revenue from a
change is false; it only closes out one class of revenue streams, the
ones that require restricting distribution of the modified
program. Other methods exist, including but not limited to selling the
results of running the program (A), selling the ability to run the
program (B), or simply saving staff time (C).

A) I wrote a 3d gas flow modelling code for a petrochemical
   engineering firm. They charged people out the wazoo for plant
   failure analysis that incorporated the results of those gas flow
   models. The investment in the program was a *lot* smaller than the
   investment in a single set of physical experiments.

B) I've wrotten programs that were installed on the clients web server
   and accessable only via paid subscription. Selling one year
   subscriptions is a lot better than selling copies - the customer
   has to cough up more cash at the end of the year if they want to
   keep using the program.

C) I wrote a program for that same petrochemical company that
   estimated the probability of the ignition of the gas clouds
   generated by that 3d model. This reduced the staff time to generate
   those estimates from days to minutes, and the development cost was
   recovered in less than a year.
