Your framing makes it seem like these companies decided to reduce the size of their products for the health of their customers. We all know they're doing it to save on costs and increase profits.

Why would news outlets go the extra mile and re-frame it as "Companies are reducing the size of unhealthy products while maintaining the same price and here's why that's a good thing..." unless they were in the pocket of these companies? That would be editorializing to me.
