I agree. I'd love to see European institutions to begin using European software and infrastructure. I feel like we have lots of puzzle pieces already, I'd add ONLYOFFICE to the mix, which would be very important to replace Google Drive / Docs / Sheets or Microsoft 365. They even have a free personal tier to test the waters.
In my experience with government organizations, the argument that public tax money should be used for public/free re-usable software instead of funding proprietary development (essentially subsidizing R&D of foreign corporations), really strikes a nerve on all administrative levels.
