Not to defend Facebook, but a failure to opt-out is not really the same as volunteering.

I find the argument made by Facebook to be sound. They're making a comparison between Google crawling the web and indexing content vs. a news site intentionally posting their content to Facebook.

The difference between getting your webpage crawled and explicitly posting on a public forum is significant. I read their comment as "users explicitly post contend on Facebook vs. passively having their content scraped by Google".

True, but you have to opt-out from Facebook too if an end user shares the link. Their argument only works if the news outlet shares the link.
