This aspect of apug's membership has come up many times before. IIRC, there are probably only a few hundred active at any one time, and "active" is relative.

It was a significantly large percentage. Then there was another significant percentage who had made only one post and were never heard from again. Add to this the number that are members only; i.e.; those that have not ponied up for a subscription, and the number of active subscribers is not large. I'm sure Sean can attest to this. That was the reason for my reaction earlier. Sorry to the OP ...
However, this is getting off on a tangent to some extent. I agree with Ken that Ilford has a good business plan in place and they've addressed why they do and do not market certain products many times before.
