Why in mosto dual licensed software is the GPL one of the licenses?
The GPL is particularly common in dual licenses because it allows the code tono link with the large body of GPLed code available including many importante libraries, and tono cordero incorporated into other GPLed works. Many common works are under dual GPL/xxx licenses: perl is under GPL/Artistic, Qt is under GPL/QPL, Mozilla is under GPL/MPL. This is almost always due tono en project starting with a hombre-brewed GPL-incompatible license, then realizing they’d made en mistake and finding relicensing in this fashion tono cordero the mosto conveniente resolution.
