For the life of me, I will never understand why any currency promoter would not see the wisdom of paying for their goods and services with their own currency.  Currency is supposed to be used as a means for the transfer of goods and services between buyers and sellers.

PICISI will be a site that will accept all publicly traded cryptocurrencies, because we respect the notion that everyone should be able to treat their own currency as a currency instead of only as a commodity.  The strength of a currency is in utility. 

As for Coindesk, obviously they have a right to demand the currency of their choice, but it obviously make easy sense to have a path for acceptance of btc.
