This is official mesage from support "If you buy additional ICN on kraken (and if you leave ICN on kraken exchange), you will receive dividends as a token owner.If you will buy more ICN tokens, I recommend you to transfer them to your ETH wallet for which you hold private keys."
This is not true. You cannot have ICN tokens on exchange and receive dividends.

ICONOMI's official statement is that if you will keep ICN tokens on exchanges, you will not receive dividends.
If any exchanges do support receiving dividends, then it's merely an exception at this moment.
