For the people who have not yet decided on a search engine. The most EU way you can go is Ecosia or Qwant as they are building their own search index.
Ecosia is my personal pick as its also aimed at planting trees and they have quite a good browser alongside it.
How would it be paid for? Subscription?
It already exists, it’s called kagi
Its US based tho, so not in the spirit of this community
