France and Germany tried their hand at a publicly funded Google (search engine) competitor [0]. It is also worth reading up on EU projects such as Galileo and Gaia-X. If history is any guide, it would not likely go according to plan.
Not sure about Galileo, but Gaia-X is not an EU project. It's a project started by a group of private companies, just because they are companies located in the EU, it does not make it an EU project.
Anyway, Gaia-X will definitely be a flop, or rather, will remain vaporware IMHO.
