Exactly my point Andy.  (and I meant to add the "Foundation" after that...my bad)

Same String = Many Things

BUT !!!!  sometimes we really should not use that Same String in 2 Wikidata Topics, but can do a little research to find the Real name that each topic should ideally be using)

One topic for the Organization could be named OpenStreetMap Foundation

Another topic could be named OpenStreetMap the service, db, map  (or if you have to say many things about each part, then ideally each should be a separate WD Topic)

Another topic could be named the OpentStreetMap API

In Freebase, we had a great way to move statements to other topics where they really should be.  This helped with Split topics.  In Freebase, we had both Merges, and Splits.   And Splits are the most painful and require nice gui tools to make moving statements around from one topic to another.  We had a great view that should 2 topics side by side...so you could move statements from one to the other to disentangle it all after a Topic Split.
