According to original report 37.41% websites running on Shopify have good CWV, while WooCommerce has a paltry 11.72%. But guys at Automattic still prefer to spend their time developing Admin and Blocks… Partially this difference can be explained by the fact that Shopify provides decent hosting with CDN out of the box while many small WooCommerce shops are hosted on some shared hosting. But there are clearly huge problems on WordPress and WooCommerce sides.
