Legal Win

2025-09-13 09:27:15

Just got word that the court dismissed several of WP Engine and Silver Lake’s most serious claims — antitrust, monopolization, and extortion have been knocked out! These were by far the most significant and far-reaching allegations in the case and with today’s decision the case is narrowed significantly. This is a win not just for us but for all open source maintainers and contributors. Huge thanks to the folks at Gibson and Automattic who have been working on this.

With respect to any remaining claims, we’re confident the facts will demonstrate that our actions were lawful and in the best interests of the WordPress community.

This ruling is a significant milestone, but our focus remains the same: building a free, open, and thriving WordPress ecosystem and supporting the millions of people who rely on it every day.

Really Simple Licensing

2025-09-12 13:18:26

It’s been a busy (and tragic) week but one of the more interesting things to launch was the Really Simple Licensing standard. I have a lot of scars from the web standards wars, so I’m hesitant to dive back in, but this is from a lot of the early Web 2.0 people, as TechCrunch writes about.

As it happens, James LePage of Automattic has spun up a WordPress plugin for it, so that was fast. Now the thing to figure out is distribution and adoption.

Account for Externalities

2025-09-12 08:58:50

When I studied economics, one of the concepts that struck me the most was the concept of externalities. This International Monetary Fund post explains it well. In short, externalities are costs or benefits of an economic activity that affect third parties who did not choose to incur them, leading to a divergence between private and social costs or benefits. They’re spillover effects—positive or negative—that the market price fails to reflect. A classic example is air pollution from a factory, where nearby residents bear health and environmental costs not included in the price of the factory’s products.

Open source is full of externalities. On the positive side, adoption creates ecosystems of developers and provides many paths of distribution. On the negative side, there’s often underinvestment in the very projects that sustain the ecosystem. I have a lot of empathy for why, when open source meets finance and private equity, things can go sideways. You can look at a business built on open source and see seemingly amazing margins—efficient R&D that compounds in a DCF model. A percent here or there over many years really adds up.

My plea to investors in open-source businesses is this: when a business is built on top of open source, incorporate a restorative investment percentage back into the projects critical to the end-user experience of what you’re offering customers. In WordPress, we call this Five for the Future, but it doesn’t have to be five percent; it could be 0.1%. Plan for it when modeling your expected IRR hurdle from an investment. Then, a few years down the line, when the small percentages start to add up, you won’t face a big catch-up or gap.

This underinvestment is itself an externality. It doesn’t appear on the balance sheet, but it can manifest in black swan events, such as security breaches or remote code exploits. Technical debt is one of the largest unaccounted-for externalities in the world today. Engineering, in the long run, is primarily a craft of maintenance rather than creation. The bulk of the cost of something comes from its upkeep over time.

PostHog

2025-09-12 08:09:36

It’s always fun to see someone pushing the limits of the web experience, as I reminisced about Flash and Dreamweaver the other day. The new website for Posthog is a delightful rabbit hole to explore, akin to a Meow Wolf, with meticulous care and craft applied to every corner of the product in a way that is both fun and playful. They even have their own version of pineapple on pizza.

What I want to enable with WordPress is the ability with thousands of plugins and themes for people to have unique, funky experiences like this on their website, while still providing a content structure that’s legible for interoperability and hacking. Major kudos to Cory Watilo and James Hawkins for coming up with this.

On WP Product Talk

I had a great chat with Matt Cromwell and Zack Katz on WP Product Talk today, mostly about the intersection of AI and WordPress, give it a watch!

Techmeme 20

2025-09-10 04:24:31

It’s New Apple Stuff day, so the headlines are being dominated by that, but it’s worth taking a step back and paying homage to the site that has been the front page of tech news for two decades now, Techmeme. I’ve been a daily visitor since it started, and I appreciate how they pair the algorithm with a light human touch to provide a wide overview. (WordPress-powered!) Fred Vogelstein at Crazy Stupid Tech has a great review of how Techmeme started and evolved.
