I believe that the term of art is "backgrounding".
As in the company provides "background" information such as seems to be the case here. Of course, this is really the company framing the conversation and deflecting the criticisms without addressing them.
I see the discussion here is largely fixated on whether this constitutes a "smear" or not. So, it seems to be working from Facebook's point of view as we are not discussing the actual allegations against them.
