With so many APIs in use, integrations, etc, there will be the potential for a lot of broken stuff. And many non-tech users won't understand why some sites suddenly stopped working. It will just present more challenges for developers of good apps that users want, in order to stop one set of specific behaviors that they do not want. But advertisers won't just go home. They will find other ways to reach people with possibly more obnoxious and/or invasive tactics. Reminds me of the spam problem. With all of the spam "solutions" and policies in place, it is now much harder than it should be for legit businesses to send emails to customers who've requested them. Yet spammers are still doing their thing with impunity.
