That's just saying how people tend to use it, not what the technology does. Namespaces/Cgroups can be used both ways, to isolate a single process (or even partially-isolate individual threads) or entire userland stacks.

The question that was asked what the technology can do, not how it's being used. What are the primitives, the atoms its made of.

People tend to use words that describe how they use things to describe what they are.

Well, take a car as an example.

The question is not what you use a car for, but rather how the car is built.

Car is a carriage-like mode of transportation.

The question was "Calling "VM-like" is not helpful because containers have also been called that, it also doesn't explain anything."

I've provided examples why "VM-like" is used to describe jails.

I think you need to look into usage of "-like" suffix.
