I am new to wordpress theme development and was hoping someone could clear my confusion regarding what the"GPL" entails regarding themes sold on Themeforest.
For Instance, If I develop a wordpress theme for sale on the marketplace, does that mean anyone can copy my work, ie, php/html/js, claim it as their own and simply give it a makeover with css and images and sell it off as there own?
Is it allowed or practiced among’st developers to study other’s themes/plugins to learn how they have been developed and use this understanding in the development of your own works?
My question stems from my basic understanding that wordpress in itself is GPL and that the themes or plugins developed by the authors hard work, are not subject to the same privileges.
These were just a few questions which popped in my head after reading an article regarding the GPL, and would really appreciate any insight on the matter.
