I'm not sure it is fair to characterize it as scraping. My understanding is that News sites voluntarily put together a little gift basket of title, image, and summary specifically because they want platforms to display it, and can turn it off with the click of a button.

My best guess is that this is actually a collective action problem/prisoners dilemma. News sites would rather not have the summary (and get more traffic), but any one news site that drops it will lose traffic to those that dont.

Because news sites can't organize and collaborate effectively, they were stuck. In this sense, the law was a win-win. Either a hail mary shakedown, or a ban on all summaries.

It is like grocery stores passing a national ban on coupons.
