This change removes the recently added feature that linked blog posts with related products through a carousel. Businesses can still achieve similar merchandising using existing dynamic website snippets, product categories, or community modules, avoiding extra built-in complexity.

This reverts commit c5c62908be621f40101e0b405375907b657ca6ee and the feature.

You can hack odoo with dynamic filter to make something similar. (string matching, or ugly categ hack)
