You are mixing up two concepts here, that of the domesticated species and the domesticated individual animal. The article talks about the former. The latter means taming an individual of a species. Dogs are by definition domesticated wolves and depend on humans for survival in general.
What about dingoes? The best guess is they were domesticated and then went feral some 5-8k years ago. These days, in places like Fraser island in Australia, you have big fences for campers to not get eaten by packs of those and you need to drive everywhere, they would not hesitate for a second if given a chance.
The aborigines (till they themself were domisticated) had dingos as dogs and my interactions with them on Fraser Island were in a way like with wild dogs who wanted to get BBQ.
Wouldn’t wolves generally be significantly less dangerous because they are generally more skittish and avoid being near humans?
One of the main issues with feral/wild dogs (or wolf hybrids) is that they are much less afraid of humans and therefore are more likely to attack livestock, pets or even actual people when given the opportunity. Under normal circumstances actual wolf attacks are (and probably were historically) and feral/hybrid dogs are just attributed to them.
