Came here because I just discovered Kagi. On the topic of de-googling, the effort is a fair point. Like the other poster said: Start small. A few months ago I moved away from Google Mail, Contacts and Calendar. After detailed research and trialing, I made the move - the practical part of it took actually surprisingly little time. I’m using Fastmail now, so at least that part Google now has only very limited access to. Might be doing the same with Kagi for search.
