It's good to differentiate truly independent tech from the unfortunately common government-pushed French-tech that are US-tech rewrapped.
e.g. Qwant is a re-skin of Microsoft Bing
It's a great move overall.
As far as I know, Qwant indexes itself and substitute with existing crawler results, which seems a reasonable compromise.
Ok? You could make the same argument about Chinese tech, German tech, or American tech.
Qwant is working on that. Together with Ecosia they're building their own index called the European Search Perspective:
"Today, Europe receives 99% of the answers to search queries from external infrastructures. We believe, however, that a higher level of digital sovereignty is essential for a functioning democracy and economy. With our new web index, we are creating a European perspective on politics, culture and values. This is a long overdue step towards more plurality in the digital world, which is also being called for by our society."
