I'm not so sure. Take a look at Google and YouTube:
YouTube regularly blocks fair-use videos (remixes, criticism, etc) because the automated filter finds something that matches and can't recognize context.
Google regularly gets DMCA takedown requests for search results that go to official websites and YouTube ads/trailers.
My Facebook feed is covered with old acquaintances sharing news links and other such content.
It seems like it would be really easy for Facebook to run afoul of this, just due to others' incompetence.
