A ruling that some of these dark patterns are valid would be a disaster to the people trying to enforce these laws, so undoubtedly they're trying to build a watertight case to prove them invalid - knowing that the companies they're trying to enforce against have ridiculous amounts of funding and entire businesses will fall if the enforcers win.
