Yes ShadowCash uses both, the Shadow token can only be used with stealth addresses (thus the untraceable and unlink-able transaction). And you are right, if Cryptonote first combined this logic into a crypto system then yes, give credit where credit is due.
I think it's important for everyone to see this is how vetting and improvements happen in the real world. You don't see any Bitcoin purists coming into this topic saying, "ShadowCash uses a blockchain? Satoshi invented that, you're just a clone of Bitcoin..." We all give credit to SN for figuring out the public ledger, solving double spend, etc. If CN first applied ring sigs & stealth addresses in it's system then we need to acknowledge that. That's what Shadow is doing too. Now, the SDC devs have innovated that idea with implementation of Shadow tokens, but the original working system (just like the blockchain system, we too are using) is another project's innovation.
This should also clarify to everyone why the XMR supporters are saying it's a clone of Cryptonote. See where they get that from? Since April 2014 they've been doing it. Bitcoin supporters would be saying the same thing if it wasn't a complete waste of time to write the sentence on the BITCOIN Talk forum.
