They seem to have obtained these coins from bittrex 3 months ago, when shift was low and cheap. Due to this being a free market, they are allowed to sell and buy as they please,no matter how unfortunate it is for others. I personally am grateful for the "cheap coinz :-)". Any allegations that this was the dev team are baseless however. Their address at https://explorer.shiftnrg.org/address/11822598910432855338S remains untouched.
