WordPress GPL Commercial Themes and Plugins
When you start getting into themes and plugins to extend your WordPress site, you need to understand what GPL and open source means. Because WordPress is licensed by the General Public License (GPL) and is an open source software (OSS) project, any themes or plugins also follow the GPL licensing structure. Many of the popular theme and plugin providers in the commercial WordPress space are compliant with the GPL, and you can feel comfortable knowing that the software they’re using is free of any restrictions on use or distribution.
Don’t confuse open source and GPL with a free price tag. It’s standard practice to charge for commercial services that abide by the GPL. Typically the commercial providers listed in this article are charging a price for their time and the services and support that come with your purchase.
