Mark Forman: Facebook needs to keep the metadata and copyright information intact of all posted images.Until they do this they will still not be the friend of any photographer.They also need to allow image protection from the point of view of the image owner in a way controlled by the photographer and not facebook.Image theft on the web is rampant and facebook has done little or nothing so far to stem this problem.

Given permission? Yes. Passed ownership? I think not.
Incidentally, some photographers do make friends (shocking, I know), and Facebook is a good way of encountering and/or keeping track of people with similar interests.
Besides the issue of credit/copyright, there are a few FB users who actually appreciate and learn from the details of photographs.
