>No one starts a project from scratch; instead, they turn to libraries like GitHub or GitLab to download packages of code already written, reviewed, and improved by the community.

Completely false on so many levels.

>Developers spend an average of two-thirds of their time adapting open-source software to their needs

No, they don't. This is just made up. Developers develop with open source software. They do not spend 2/3 of their time "adapting" it.

>Our structure is quite unique: we’re a limited liability company owned by the German government

I know of one similar corporation. Deutsch Bahn.

>which is maintained by people selflessly.

This myth comes up again and again. It just is not true. A large part of open source software is created and maintained by corporations.

>Most people have never heard of curl or pi [Python], or the other 60 technologies we work with. But if this software goes down, suddenly the payment systems stop working.

This persons does not understand what python or curl are. They do not "go down". This is just someone not having a single clue what they are talking about.

>You really need to understand how software developers work and how the open-source ecosystem works.

Well. I guess you don't, to get 20 million in budget from the government.

>We face a classic commons problem: everyone relies on open-source software as a foundation for building their own developments, but no one feels responsible for it. Why should I invest in open-source software if my competitor is also using it and not paying for it?

Again. A total myth, this person has zero understanding of the open source landscape.

>What does open source contribute to the debate on reducing the carbon footprint of technology?

Truly an enlightening question. The answer is even worse.
