The link to the webpage works. The link in your post above and a lot of the links in the article don't. I don't condone venomoids in general because of all the amateur surgeries, however there are a few vets that do it and they do complete duct and gland removal. As I said though, it's impossible to tell if the surgery was legit or not. A certificate can be faked.
I do have a lot of problems with the article, though. The author, whoever it is, seems to be inconsistent in his views. A vet doing surgery with anesthesia is unethical, but a farmer doing an amateur castration on a Bull is OK? He says true venomoids still give a nasty bite, but then brings up them killing rodents as proof of envenomation? Of course a venomoid Gaboon can kill a rat by stabbing it with 2 inch fangs! I don't trust sources that present opinions as facts. The opinion that only rank amateur keepers keep venomoids is not true either. I was at NERD's facility in 2001 and they had a venomoid Eastern Diamondback Rattlesnake in the shop as a shop pet. Yasser Mustafa of Spitfire Reptiles took heat on the venomous forums when someone posted a pic of him letting his venomoid albino Monacled Cobra bite his hand.
