The Open Source Maintenance Tax Nobody Budgets For

The licence is free; the fourteen years of feeding it are not. Here's the maintenance tax nobody budgets for — and how to fund the load-bearing “free” software before its lone maintainer walks.

“Free” open source is a budget illusion. The licence costs nothing, so the cost shows up nowhere — which means it lands, untracked, on the nights and weekends of whoever ends up maintaining it. The puppy was free. The fourteen years of feeding were not.

This matters most when the free thing becomes load-bearing. A library you adopted casually is now in the critical path of revenue, patched by one person who could leave tomorrow. You've built a dependency on goodwill and accounted for it as a saving.

If something is genuinely load-bearing, fund it like the asset it is — staff its maintenance, pay for a supported distribution, or sponsor the upstream project so the maintainer who keeps your business running can afford to keep doing it. None of that contradicts using open source; it's how you use it responsibly. The danger isn't the price tag. It's pretending there isn't one.

Total cost of ownership is the full lifetime cost of something, not its sticker price — acquisition plus integration, operation, patching, support, and eventual retirement. It's the difference between what a thing costs to buy and what it costs to have.

This is where “free” gets expensive. Open-source software has a real TCO; the licence was just the cheap part, and the maintenance often lands, untracked, on someone's nights and weekends. Anything load-bearing deserves a TCO view — otherwise you've deferred a cost into invisibility, which is not the same as avoiding it.

And built the whole stack on the deal.
One maintainer, unpaid,
Got tired, and strayed—
“Free” has a bus factor. For real.
