Google is negligent in failing to block malware ads. They chose how to build their system, and they could have build a system without this vulnerability (but it would be less profitable). Just because they are the biggest certainly doesn't mean they are ethically innocent here. They choose to maintain a business model that requires third party scripts - which is a conscious decision to harm the audience at the expense of their patrons. Their greed needs to be called out, or else people will continue using them as a shield against any critical call for improvement in the fraud-rampant online ad economy. Google may be the best there is, but that says more about the lack of morals in the ad industry than Google's high-ground.
