You clearly didn't read it. A direct quote:

> At minimum, ranking algorithms with this much economic consequence should be auditable.

"At minimum". Immediately preceded by a paragraph starting by "For policy", with sentences like "If discovery now shapes small-business survival, then competition, fairness, and urban regeneration can no longer ignore platform ranking systems" or "tools of local economic policy".

That's perhaps not an outright call for regulation, but it's certainly suggesting it's warranted.
