All credit cards that I know of in the US now charge the same fee for all foreign transactions, regardless of currency, which defeats the purpose of DCC. I am not sure about issuers in other countries but I imagine it's similar.
The DCC perpetrators can say with the same strength of conviction as holocaust denialists and Japanese history revisionists and say that's the issuer banks' greed, not them.
