It does seem extreme. I think that on a site dedicated to film there should be a distinction between images pertaining to artistic merit (or indeed photographic process) and those which are merely quick snapshots to illustrate some technical point or piece of equipment as you have described. I can understand that pictures on a film-only site which are of an artistic or demonstrative nature should be shot on film and anyone visiting the site would expect this to be so. Pictures which are there to quickly illustrate a technical discussion are best shot on digital (or a Polaroid) for immediacy and this is one thing that digital is very good for. It seems like cutting your nose off to spite your face.
