Those analytics are for authoritative queries against the domain(s) that you have on Cloudflare; not for queries to any domain.
Not logging _recursive_ queries against their public resolvers - and it's those recursive queries from end-users that hold the biggest risk to user privacy - is an entirely different thing, and these two systems can co-exist.
Cloudflare could do as google and not include any query that comes via the public resolver. Any DoH query would thus be a blackhole in regard to analytics and only display data from users who used someone else recursive resolver for the query. In that way no logs from the public DNS resolver ever ends up as data, the privacy document is followed, and companies can not buy query data by becoming customers to Cloudflare.
Personally I don't see how that product can coexist with the privacy policy.
