I'd guess that the DDI group figures represent the actual subscription numbers rather than a minimum (which often gets tossed around). As I understand it, the system now automatically creates a forum identity alongside a DDI login even if you don't visit the forums, and adds that into the DDI member group by default. That would make the DDI subscription numbers much lower than some would want to put it, and when combined with the money that was spent getting DDI up and running (plus ongoing costs) it makes it a toss-up if it's considered a success by WotC or not (especially if it ends up eating into physical book sales).
Another point since it was mentioned earlier. Hasbro doesn't get involved generally, but they do if things go downhill. It might be inferred from what was going on around the time that Greg Leeds came in to head WotC (mass DDI layoffs with the "digital reconsolidation" when they moved everything back in-house). Leeds came from elsewhere in Hasbro, and as I understand it was put in place to put things back in order. This is a combination of second hand info from folks there on the DDI side of things at the time, and my own inference, but it seems reasonable given how much $ was spent at the time.
Actually my friends that don't have forums accounts and I decided to check to see if what you said is true. We could not find them listed anywhere with a forum identity in the DDi group.
