So I'd wager the approach was successful, though not necessarily the desired results. However, if the rest of the world followed suit, they can't host snippets anymore and they'll be forced to pay or give up that feature, no?
Doubt it would happen, because if suddenly almost every news publication refuses to allow their news snippets to show up on Google, those publications that decide to go against the grain and personally allow their news snippets to show up on Google stand to gain a lot from it.
