I think you are being unreasonable.
Do you imagine for a moment that the Typhoon drivers are likely to be unaware of TCAS?
It is a spectacularly simple system which is why the idea is very clever and very effective in the environment it is designed for, ie unmaneuverable aircraft that proceed in a stately manner about the skys operating in a system designed to ensure that they never get close to each other.
That does not really describe a modern military aircraft.
