For clear trademark infringement or license violations, sure.

However, it'd be permissible, as I understand it, to build re-label-ware (not necessarily malware, but simply low-effort software built using FOSS foundations) using MIT/Apache and other permissively-licensed software and to publish that on app stores with price tags attached.

I have to admit: I'm not familiar with the types of apps that the policy intends to handle in practice -- but re-label-ware would seem like a rational opportunity for developers to pursue in a payment-enabled marketplace without rules to prevent them.

That sentiment doesn't sit right with me somehow. Computers can run software, and attempting to gatekeep that process (in an evolving and culturally-diverse world) seems like a path fraught with problems.

Having transparency about what software is intended to do - and perhaps system-perimeter observability that helps users (and, with their knowledge, their friends and colleagues?) to monitor what it has really been doing (to inspect whether that matches their expectations) seems like a potential space for opportunity.
