Google will notify websites that contain these types of advertising using Ad Experience Report. If they fail to meet the requirement within 30 days, the ad will be blocked by Google, even if the ad is owned or sponsored by Google - beyond this time they will have to submit an evaluation and Google will consider it to show Marketing advertising back.
Google says the goal of this is to help remove annoying ads on the Internet. But looking closer, it must also be seen that this also gives Google more rights to live on the Internet advertising market that they already hold.
