I do think it's good that you can now try it out without logging in, but using Cloudflare with aggressive fingerprinting does go a bit against the whole idea of data protection. If you're already being tracked as a trial user, why would you want to give them your payment information, which would only lead to even more tracking? I'm a Kagi user myself and enjoy using the add-on to take advantage of Privacy Passes. But now I have to assume that I'm still being tracked and that my searches are being linked to me.
