Welcome to our second episode of “Value in Open”, a podcast by Meilisearch about how to do open source as a living. Today I’m speaking with Mats Alm and Jan Källman. They are brothers, and together they have created a company around EPPlus, which is a spreadsheets library for the .NET ecosystem.
EPPlus started out as a regular, open source library, using the LGPL license. But Mats and Jan ran into a classic problem in open source: They made something so popular that it became unsustainable for them to keep developing it as a trivial side project. Faced with the options of either leaving the project or going all-in, they chose the latter. But the way in which they achieved sustainability is quite unconventional by current-day standards.
They didn’t have a product that they could naturally build a commercial service offering around. And their product was so easy to use that there was no point trying to charge for support. The path of least resistance for them, was to put a price tag on their code. No fancy workarounds. Just write code and sell it, using the PolyForm NonCommercial license, which you can read more about in the show notes.
Current-day open source licenses are code-first, developer distant second. They do not take the developer’s well being into account. Standard open source licenses don’t try to set the developer up for success; their only concern is ease of adoption for the code, at any cost. I’m speaking here as someone whose personal idea of a license utopia is a world where the vast majority of software exists under MIT style, permissive licenses. That’s the end-game I wish for. But I firmly believe that getting there will require a mix of licenses that challenge and expand our idea of openness.
Open source has an exploitation problem. The largest companies in the world have figured out how to extract massive amounts of value from open source creators without contributing a fair share back. For non-commercial users, PolyForm NonCommercial functions much like any other open source license. Source code is available and it can be modified and redistributed. Only for commercial users do the rules change. Only the people who are using EPPlus to make more money have to pay for it. There is a beautiful simplicity to that.
Is this license the solution to all our problems? Not at all. Will it fit every open source project? Nope. Is it a good fit for EPPlus? With enough income to pay for two full-time developers, I would call it a raging success! Please keep an open mind, and enjoy the episode.
Big thanks to Jakob Terjesønn Rypdal for the awesome intro & outro tunes!
