The fix is out. Is it in?

Almost four years after a free fix shipped, about one in eight Log4j downloads was still a vulnerable version. Now AI has bank regulators counting the days. Why private copies slow the fix down, what the banks' new alliance changes, and the question to ask your IT team.

A long till receipt listing licences, cloud, add-ons and contractors, torn off just below the word TOTAL.
Article Open Source Digital Sovereignty

The bill nobody can add up.

The Dutch government has a Linux desktop on trial, no new money for its digital autonomy plans, and no total for what it pays Microsoft. Leaving shows up as line items someone must sign for. Staying hides in budgets nobody adds up.

Mock AI model page labelled "Open Source" but marked "not an open release," with a locked, disabled "Request access" button and a "Sold via a private cloud" sticker.
Article Open Source Digital Sovereignty

Open in name only.

Germany spent public millions on a "Sovereign Open Source" AI, then gated it and let a vendor sell it. Switzerland and the Netherlands show the difference: real openness is a mandate, not a label.

A sleek black premium product case marked "Jev," secured with a heavy steel padlock that is hanging open and unlocked.
Article Open Source Digital Sovereignty

It was never locked.

The year's most hyped AI model arrived with 40 million dollars and a wall of attention. Within days, open versions you can download and run yourself already existed. Here is what the celebration missed, and why it matters for digital sovereignty.

Built to be paid. Easy to skip.

A new fee finally asks companies to pay for the open source they profit from, then hands them a legal way not to. Why it runs on goodwill, bills hardest the ones least able to dodge it, and what a working funding model still has to solve.

Update Open Source Digital Sovereignty

Every one of these jobs needs a name on it.

When you leave a proprietary vendor, you inherit the jobs it used to do: governance, legal, security, and giving back. Use our new free tool, the OSPO Roadmap, to map those jobs, track where you stand, and name who owns each. No login. Live now.

One Million Downloads. Zero AI.

One Million Downloads. Zero AI.

An office suite just set an all-time download record for what it left out. LibreOffice 26.8 hit 1,031,162 installs in a week with no AI, and a million people were escaping the feature Microsoft keeps adding to yours. In rented software, the next change is never yours to make.

Open Source doesn’t fail on the code. It fails at 2am.

Open source rarely fails on the code. It fails when something breaks and no one is accountable to call. Today I'm opening OpenTechHub's Service Provider layer: a directory of verified companies that build, host, and support open source, so anyone leaving vendor lock-in has somewhere to turn.

Open Source: give back, or pay forever.

Open Source: give back, or pay forever.

Most companies quietly maintain their own private copies of open source software, and the upkeep costs far more than anyone puts on the books. The Linux Foundation measured the bill. Contributing your changes back is the cheaper path, and this is why forking almost always loses.

Open Source is free until it isn't.

Open source is not the opposite of paying for software. Four business models hide behind one label: foundation-run, open core, source-available, and support-funded. Buy a stack and you inherit all of them. What breaks on day two, and the four questions to ask before you sign.

Europe had a Sovereign Cloud. Customers left it.
Article Digital Sovereignty

Europe had a Sovereign Cloud. Customers left it.

Microsoft built a sovereign German cloud and locked itself out of it. Customers left anyway. The real premium was never just the money, it was capability, and Europe is now writing its cloud sovereignty law around a gap it never closed.

You can run it. You cannot use it.
Article Open Source Digital Sovereignty

You can run it. You cannot use it.

A frontier open model now runs on a desktop. It writes five words a minute. I tested a smaller one on my own machine and it ran slower than someone reading aloud. Running these models yourself is real. It is a fire escape, not a workplace, and there is no third state between working and gone.

Open Source did not fail in AI.
Article Open Source Digital Sovereignty

Open Source did not fail in AI.

Open, capable, sovereign: in AI you get to pick two. The frontier models are proprietary and revocable, the open ones you cannot run or cannot match, and even Europe's champion runs on chips it will never make. Sovereignty is not the model you pick. It's the weakest layer beneath it.

Digital Sovereignty isn't for Sale.

"Buy European" has become Europe's answer to digital dependence. But a European vendor is one acquisition away from being American, and hosting on home soil won't stop US law. Real sovereignty isn't where your software comes from. It's whether you can leave it.

You do not need an Open Source Program Office.

Every digital sovereignty talk ends the same way: set up an OSPO, and the idea gets filed under someday. But the office is not the point. It is a container for the jobs your vendor used to do, priced into the license fee and now yours to own. Name who owns them and you are ahead of most.

Google released a folder of text files.

Google published the Open Knowledge Format, an open, vendor-neutral way to hold the knowledge your AI reads: nothing but text files. Then it bundled its own tooling beside it, every piece pointing back to Google Cloud. The format is worth taking. The strings are worth cutting.

Digital sovereignty is not a product you buy. It is a stack of unglamorous decisions about where your data lives. A personal look at the foundation layer beneath the apps, the storage, code, formats and backups, and why that is where your freedom actually lives.

Nothing to Build. Nothing to Fight Over.

On June 17, Germany and France signed a joint definition of digital sovereignty. Every past attempt, from Quaero to Gaia-X, died the same way: a fight over whose national champion wins. This time there is nothing to own. They are writing the rules instead, which bind all 27 EU members, not two.

Europe left Microsoft. The Documents didn't.
Article Open Source Digital Sovereignty

Europe left Microsoft. The Documents didn't.

Euro-Office launched as Europe's sovereign alternative to Microsoft 365. Then it made Microsoft's OOXML the default format, not the open ODF standard. Why that default quietly hands the document layer back to Microsoft, and why open formats, not European servers, are the real test of sovereignty.

Open Code has no Nationality.

Europe just unveiled its long-delayed tech sovereignty package. Even a big tech lobbyist found opposing it dispiriting. The real fight now is between two kinds of sovereignty: the kind that builds walls, and the kind you can read, run, and trust.

Your Data has a Nationality.

A Dutch 'sovereign' cloud almost became American overnight, and only a last-minute government veto stopped it. Real digital sovereignty was never just about where your data sits. It is about whose courts can reach it, and Europe's billion-euro plan still misses the point.

Open Source is not a gift. It is a contract.

Google is shutting down Gemini CLI and replacing it with a closed-source tool. 100,000 stars, 6,000 contributions, hundreds of volunteers. Enterprise customers keep access. The community that built it gets 30 days. When the value lives in a proprietary API, even forking cannot save you.
