> Code bases are on GitHub

Not a very solid way to move away from American big tech :/

If the move away from American big tech is for practical reasons rather than political, there is no harm in using GitHub. The worry with using an American firm is that the US government could force the company to handover confidential information, or shut down access.

For open source code, there is no risk of confidential information being given to the US government (since there is no confidential information), and moving to another forge would be pretty simple if necessary.

The other commenter nailed it down. But I want to add that removing dependance on US companies is not some kind of spiteful act. It's purely down to both privacy and reliability.

Having private companies in the US becoming more involved with politics is fine for the US apperantly, but the EU just don't want to be involved.

Maybe they have local copies as well, and just figured they might as well take GitHub’s free bandwidth and social networking features.

This is probably just the first big step (communications) in a series of big steps.

React is also from US, no?

I remember seeing some projects by the French government on their self-hosted Gitlab. Maybe these are just public mirrors of their private repos?
