The GPL seeks to eliminate that right "to charge more [than

The GPL is adopted voluntarily by people who choose to distribute
their software under it. Rather, the GPL eliminates the ability
to be charged zero for those developers who want to incorporate
GPLed code from other sources but not allow their users the
freedoms that they themselves enjoy.
The bitter complainers want to use GPLed software in their
products for zero charge but do not want to meet the conditions
of the license. They wish to steal the work of the developers of
the GPLed code and not provide them with the recompense of
assuring the freedoms of the users of their work as they have
specifically asked.
