Those laws have been tried in several European countries, and the strategy is always the same:

- Google had to exclude the plaintiffs or shut down the service because they were not allowed to operate it without a license, and could not get a license in time;

- Deprived of Google traffic, the News site audience suddenly dropped and they granted Google a free license, as an emergency process to keep the lights on;

- Google keeps that free license for all sites, every other operator simply doesn’t have the capacity to reach out to every site, so competition to Google is completely killed.

The worst part of all this? There is a very old convention, well enforced, that already handles it: robots.txt

Yes. It was impossible because it was always single sites doing it, and that doesn't work. To prevent that scenario, this law is for all news sites and doesn't allow free licenses.

No idea how it'll work out.

Either Google will pay... or they won't. If they won't, nobody can find European news articles, and news traffic drops, and news sites get financially hurt (just like it's played out several times in the past). Then they'll get the idea that the law was a stupid idea, and work to get it quickly changed.

If I understand correctly, which way this goes is completely at Google's discretion. And Google hasn't shown inclination to cooperate with such schemes in the past...
