I wonder whether THAT is the reason.  Because then they should have banned the DAO too...

The real test of Apple would be if they accepted monero and ZCASH.  Then we would know that it is not the anonymity but the financial structure, as you say, that was the reason for banning DASH.

BTW, ZCASH will, even more than DASH, fall in the illegal securities trap.  Unless they rendered it legal.
