Code has nothing to do with their removal, the ‘old code excuse’ is a myth. Make BPO’s / BPC’s defunct / production 0, and they will die out naturally. Put NPC buy orders up for them and they will die out even quicker. Dont know how many of you were around for when they got rid of SBU’s, but thats exactly how they did it
They are here as CCP has either decided to keep them, despite what they said when citadels came out, or they are being lazy… take your pick
