But they are not sharing stories, they are sharing "news" and "facts" in whatever format and conveyance.
They still own the authorship. When you write an obituary, for example, and give it to your local news paper, it is usually spelled out in whatever submission process that you are granting them rights to that content.
You can say, the fact is XYZ died.
You can’t copy the obituary in full from the paper/site without some sort of permission.
Sure, you may have a technical argument, but you would spend thousands in court arguing that fact. Look at the Righthaven lawsuits. They ended up losing in the end, but not after they got tens of thousands, if not hundreds of thousands from websites and many sites spent many more thousands in legal fees fighting it.
It isn’t worth it. Just go with the cleanest legal route which is to use the paper’s approved sharing methods.
