- The Hobbyist Maintainer Economic Gravity Well 11 Jan 2026 In the OpenSource Supply Chain discourse in the past few years, we got many versions of the same article. The title is usually something like “unpaid maintainer of library X demand Big Company to shut up or pay them mon…

- You Are All On The Hobbyists Maintainers’ Turf Now 1 Apr 2024 For quite some time, I have felt some unease at the public discourse around OpenSource. In the past few years, we have seen a growing discourse around the sustainability and security of the large body of OpenSource soft…

Open source won because it let companies bypass procurement, legal review and contracts, not because it was free of charge.
FOSS solve that problem far more than it solves “we don’t want to pay”. Most corporations would be surprised by how cheap it would cost them to pay for the FOSS software they use.
How FOSS Won and Why It Matters Said 16 Nov 2025
Any fix for open source that recreates the friction of a commercial supply chain is dead on arrival, because that friction is what open source escaped.
You cannot go back. If the solution you offer recreate any of the Supply Chain framework problem, then your solution is Dead On Arrival.

Charging large companies for a licence sends them back through procurement, so they drift to a worse free alternative rather than pay.
Making licenses suddenly commercial for big entities? You are forcing people to go back through the Procurement process. They will shift over time back to a FOSS solution, even if it is less good.

The same absence of contracts and lawyers that let companies adopt open source freely is what let experts publish it, and raising the bar would break both.
It significantly lowered the bar to production. It is how we got the whole society to run on software. If you make it harder for hobbyists maintainers, you are going to crash society.
How FOSS Won and Why It Matters Said 16 Nov 2025
Most of the code the world runs on is maintained by hobbyists with an hour or two a month, so any proposal that needs more than that will simply be ignored.
It means that anything you offer must fit in 1h per month. That is it. And if it does not, if it needs more involvement than that, we, as maintainers, will not do it. At all.

Any plan for open source sustainability or security that is not built around hobbyist maintainers will achieve nothing.
If your plans for open-source sustainability or security do not align first and foremost with this population it is not going to achieve anything.
You Are All On The Hobbyists Maintainers’ Turf Now Said 1 Apr 2024
Veterans of the 1990s free software movement do not understand the world today’s maintainers work in, and should listen before proposing fixes for it.
This is not the same world that you were part of. The complexity is off the chart; we are hidden layers and layers under the scaffolding. And we are used everywhere.

Maintainers of widely used open source software are not adequately funded, and that is a real and unsolved problem.
Hell even worse, a lot of the libraries that underpin the fabric of what we all call the digital economy have trouble getting enough money to pay for food.
I am not a supplier Said 31 Dec 2022
An open source maintainer is not a supplier: there is no relationship with the companies using the code, so they cannot impose requirements on the person who wrote it.
We are not suppliers. All the people writing and maintaining these projects, we are not suppliers. We do not have a business relationship with all these organisations.
I am not a supplier Said 31 Dec 2022
If a company wants a maintainer to work to its standards, it has to start paying them under a different licence first.
But to do that, I am going to have to become a supplier. Which means you are going to have to start to pay me. A fair price, that we can negotiate. Under a different license.
I am not a supplier Said 31 Dec 2022
The warranty disclaimer in a free licence is the real deal being struck: the entire risk of using the code falls on whoever uses it.
If you use this, I owe you nothing. At all. We have no relationship. I put this up online on the condition that if you use it, all the risks are on you.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
