This solves multiple goals: hide identity, show anon-source exists, and show facial emotions to viewers.
The latter is a huge win for making media people want to watch. Same reason all those cable stations segment the screen into four with a face in each corner, or why streamers overlay their gaming with a their face on a webcam. We like faces.

I get that people like faces, but the news should be real.
Maybe I'm expecting too much of the BBC, but it seems pretty short-sighted to start carrying fake news, even if they are only starting with a fake face.
