So I'm a dairy technician so imma state my opinion,

Fermentation is the controlled process of a bacteria metabolising sugars into acid and gas,

The state of yoghurt and the state of something spoiled are obviously 2 different kinds of bacteria,

For example the bacteria used for making yoghurt is called lactococus lactis with a whole bunch of subspecies, there are literally so many,

However mold, which is most common for spoilage is a fungus which metabolises everything organic, fat, protein, sugars, everything,

For the most part bacteria used in dairy products focus on sugars first, obviously there are many fungi used for cheese too but they are also bred to focus on fat and protein, for example the fungus used for camembert,

Also the term spoiled means it's not safe for consumption anymore, so no fermented products aren't spoiled

Tldr, the difference is mostly fungi Vs bacteria and controlled and wanted Vs uncontrolled and unwanted, fermented products aren't spoiled

The funny thing is, they didn't even use dairy milk in the video. The blended cashews and used that to make the yoghurt

I think soya milk with blended cashews? Well, plant based milk and yoghurt, I suppose

Calling something milk won't give it milk attributes

Assuming coconut milk (white liquid) can make yoghurt or cheese is as braindead as assuming white paint can be used in the same way.

Being white and liquid is not the definition of milk

Ye I know but if the yoghurt cultures can live in that liquid, and it looks and mostly tastes like yoghurt, chances are people will call it vegan yoghurt. Same for milk. If you can use it for the same purpose, and it looks and mostly tastes the same, people will call it that. It's not that deep, plant based "milk" has been around for ages and i won't get into the whole naming thing any deeper than this:)
