There are guidelines about what information posted on social media can be used elsewhere, from ipso and probably also from the service providers. But they're much the same rules as reporting on something overheard in a pub, there has to be a case why it shouldn't be and even that can be overruled if it's in the public interest. There is no licensing that could stop you reporting on something said elsewhere, there may be some requirement to state where that came from "Mr X wrote YYY on facebook..." but I'm not sure.
The problem with Facebook and a lot of Social Media is it is not so much deciding to "exclude yourself" but being unhappy about or unprepared to accept that "you" become the product and you need to relinquish aspects of privacy (something I don't have to do watching e.g. my TV broadcast news).
Yes, I get that and I would agree if it was exclusive content, in the context of this thread I've seen no examples.
