I think if you buy a book from Amazon or elsewhere, and I have books from Fictionwise on my Kindle, then you need to realise that Amazon knows what you have on your Kindle by the book metadata, when I load books from other sites via Calibre I don't change any metadata as it doesn't bother me.
On the other hand I have 100's of PDF's and converted RTF documents on my Kindle which are fan fiction, so (as far as I know) they have no proper metadata so all Amazon could know is I have 100's of personal documents on my Kindle loaded via my pc.
I have nearly 900 items on my Kindle now, and only 200 are proper books, and less than 100 came from Amazon
