The problem is this: I isn't my dataset. It's data loaded into an 
instance of Virtuoso.

To you the first piece of that is an owl:sameAs assertion. That's 100% 
fine for you, but that isn't true for everyone else. It just isn't.

No, DBpedia doesn't have a billions of entities, that just one dataset. 
The Virtuoso instance in question is a LOD cloud cache instance i.e., 
we've loaded the available datasets into the instance. From that I 
produce a variety of demos. Just as anyone else can since the endpoints 
are all public.

Again, context infidelity. In due course you will understand my point. 
For now, we can go back an forth. You characterization is 100% inaccurate.
