All true, and it shows how everything is solely done for optics, and any flimsy excuse is used to instantly claw back at any kind of transparency/openness the very second it arises. Non-technical people making this decision because they believe there's even a 0.1% chance that they'll be blamed that they "didn't do enough" when they didn't go closed source and a vuln is found. And 2026's extreme greed and selfishness (and yes, average greed level does change over time, as with every single cultural trait) means they gladly make that decision at the cost of the common good.
Do always keep in mind that the private sector isn't any better on these things.
The only exception is if there were significant changes to the code after it was closed given that won't be read by the attackers or the LLMs, if you are using them locally.
They can use LLMs internally to find bugs privately without revealing the source code, a step ahead of the attackers.
We have just seen the Copy.fail disclosure disaster that was discovered by someone using a LLM and released a zero day without a clear fix and descended the community into confusion / panic.
Given that powerful LLMs exist both open and closed weight models, open sourcing everything for the sake of it makes less sense and there has to be a balance especially when it is used by hospitals.
I've been chatting with CISOs, CTOs, and other peers for the past few weeks (some of whom are F50s) about this, and their default gameplan now is to pause OSS contribution and usage until AppSec teams reach a point where they can easily validate and fix issues within a day. Traditionally, end-to-end response times were in the 8-10 day range which clearly cannot hold today.
I don't think it's the death of open source, but it shows how the economics of open source turned into a tragedy of the commons, with maintainers not being provided the resources needed to sustainably maintain projects.
It also is an admission of how organizations never prioritized security for decades both within engineering and organizationally.
If OSS lovers actually care, then they need to put their money where their mouth is, stop being idealistic, and think about either going open core or getting formalized funding and sponsorship. Adopting much more restrictive licenses that also allow commercialization by project owners is also critical. A GNU style project that exists on the goodwill of a couple of ideologically aligned individuals will not survive.

I can't sign because the cloudflare verifier says I'm not human...
Are you indeed not human? Because in that case I don't think that you should sign petitions for the UK government.
