It's nothing about drops. It's about control.
They're moaning about having to comply to Nominets terms & conditions & control. Someone will correct me no doubt, but before Nominet domains were registered and controlled at root server level and also had different conditions regarding ownership. Under nominet there's no 'ownership' of domains just an entry on the register, paid for biannually. Also pre-nominet have no complience to the DRS. Dispute was normally at court level.
