Re: it's actual business - offering domain registrations
I would agree, except that you can't (so far as I can tell) actually buy a domain from Nominet. It's all resold.
Not so. Nominet (and many other TLD registries) provide some sort of "registrar of last resort" service for those who choose not to go through a registrar. IIUC the price for that is at least 100 times the price to its registrars. Not surprisingly, this service is rarely used.
Not being in the business I have no idea what is the markup on reselling .uk domain registrations.
The article says Nominet sells names to its registrars for £3.90/year. Deduct that from the price a registrar charges you and voila! you have the gross markup. And in some cases, those markups really are gross.
Nevertheless I don't get why Nominet -- or anyone else awarded the golden chalice of allocating ccTLDs -- would want to piss it away to the likes of, I dunno, Verisign.
Taking .uk away from Nominet isn't going to happen unless the company does something really, really bad: going bust, money laundering, bribery, and so on. You then have to figure out who takes .uk out of their hands and decides who replaces Nominet, how that gets done, creating an oversight body, identifying the contract parties (and terms), transition/migration plans, etc.
