October 15, 2023 — The WordPress.org plugin directory requires that all plugins must be compatible with the GNU General Public License (GPL) and recommends GPLv2 or later as the same license as WordPress itself.

This includes third-party libraries, code, and images. With today’s modern development practices and easier contributions on git-based systems like GitHub, you may not even notice a dependency being added to your project.

This talk explains how to use GitHub Actions to scan your current codebase and ensure that all future pull requests and commits similarly ensure that all third-party libraries (aka dependencies) are GPL-compatible.

August 26, 2019 — I’m going to share the story of a premium WordPress theme from Themeforest with 100K customers that decided to change its license to full GPL after 5 years. As the CEO of my company I had to be aware of business implications and risks attached to such a decision. Before making this decision at Artbees we were very much concerned about the impact this will have on our sales, our brand and the future of the theme. After a short introduction of GPL license, I will explain the results of this decision, steps we took to execute the relicensing process, market’s reaction to it and if it was rewarding or unrewarding and finally the state of my company and our theme after going GPL.

October 10, 2017 — The idea of building a business on open source software may be old hat for most technologists, but for many people in more traditional industries, the concepts around using and contributing to WordPress may seem quite strange. Can a program you get for free be any good? How does the licensing work and what the heck is a GPL? Who do we call if it breaks? Who’s in charge of this thing? Sharing technology with everyone, is that safe? Wait, you wrote some code for us, and now you want to publish it for anyone to use, for free? We’ll answer these questions and more in a discussion of how to get OSS buy-in from the whole newsroom — lawyers, executives, and IT departments included. Along the way, you’ll get a refresher on making the most of the open WordPress ecosystem, whether you’ve been a part of this community for 13 years or 13 hours.
