I think it was last year that there was a good presentation from them about how they were going to use ZKP and it was indeed very trust inspiring. But do you think the latest digital wallet solution from eg Danish government uses ZKP? Of course not!
I have to say that the tune they play at FOSDEM and what we see put into production are just two different things.
Even if the pace is frustrating, there are still pockets of genuine open-source adoption in the European public sector. For example, we're seeing projects like Germany's OpenDesk or various municipalities moving toward Nextcloud and other sovereign cloud solutions.
The EU Open Source Strategy[0] was announced just under a month ago and it specifically mentions the EU Digital Identity ecosystem, including the European Digital Identity Wallet (EUDI Wallet) mentioned in the article. I agree with OOP that the requirement of an Apple or Google phone goes against these ambitions, and I will contact my elected representatives.
