There's a difference between data sent to the website provider (and through it, indirectly to third parties), and interactions between the browser and third parties. The linked ruling forces the provider to ask the user for consent for third parties (even though the provider has nothing to do with the interaction!), instead of mandating a direct opt-in interaction between the user (agent) and third parties.
Imagine embedding many social media sites. Instead of forcing the social media sites or browser vendors to create embeddings that ask for consent themselves, the website provider has to ask for consent on behalf of all external sites before loading any content. As a web developer, this is a nightmare.
