Two-way hyperlinks and an integrated core of micropayments and publication have yet to be realized in a substantially useful way. Ted absolutely bears a lot of the responsibility for this, as he's been given resources to build such a system multiple times -- but that speaks to his project management capabilities, which are a different matter.
My read is that Ted isn't nitpicking the details. It's not that the same goals are being accomplished in some less-than-perfect way. The key point of contention appears to be that major portions of the vision are still on the table with no widespread practical or workable implementation, not because the technology is incapable, but merely because people don't understand either the original concepts enumerated as hypertext themselves, or don't see any value in them. Perhaps there isn't value, I don't know. But Ted clearly thinks there is, and is frustrated by a world that is humming along without these components that he's been trying to extoll for 50+ years.
It also must really chafe to have people hijack the terminology that originally encompasses a broad concept, and pretend like some vague, minimal similarity in an otherwise-adulterated system is the full realization of said concept. I sympathize greatly with Alan Kay, Ted Nelson, and other visionaries who've had their concepts co-opted and misrepresented by profiteers, much to the detriment of the world as a whole.
