Yeah, it's always out of focus.
It's not, it is either out of focus on the sides (which does indeed looks like it is out of focus) or sometimes it is in focus on one side and the other side if out of focus (eg. in the podcast). I think it just can't focus on the whole "scene" at once.
As far as I understand it, they bought a (good) webcam, but I am a bit afraid that it just can't handle this large of a group. I think it just is unable to get this big of a place in focus at once as it is manufactured for use at a PC, much closer to the people it needs to focus on (where I am sure it will have a sharp/good quality image).
That said, it is possible there are ways to improve the way it focusses or something (I am not that big of an expert as far as camera's and webcams go).
But yeah, I do agree it is very noticable.
However, I don't think they can fix it completely with this camera unfortunately (I hope I am wrong). I am sure they are doing everything they can to get as much into focus as possible.
