No voting services intent on financial matters care at all about content. No tweaks to rewards curves or curation splits will change that.

At best some curation services like @ocdb seek to reduce financial manipulation, but they cannot compete with stake.
Eliminating incentives to corrupt curation is possible, and will solve the problem with facility and simply.
