The post sounds like that wasn't possible; that this TLD operated by exception with third-level domains. It would be like asking why you don't just register smith.uk instead of smith.co.uk: because you can't (https://en.wikipedia.org/wiki/.uk#Second-level_domains)

That's just my reading of the situation though. The person could now hope they're the first to claim their second-level domain once it becomes up for grabs, but there's probably a dozen other people with a fraser subdomain that would want the same, plus however many hundreds of scalper scum. Probably the best you can hope for is that whoever does get it, has the decency to honor the original third-level domains for a reasonable fee

You can. Anyone can register a .uk, and you don't need to own the .co.uk
