I think of tui as “text user interface” and use it as a broad category but mostly for more advanced clis that have a graphical quality to them despite being text based, such as ranger or slack-term. Some tuis even have mouse controls!

A cli is a ui. I know that’s pedantic but this is Linux memes

Advanced users would still benefit from good design.

Ui designers should not presume people are familar with the ui. That’s not design.

It’s is not either or. Also good cli require an eye for design just like gui. Lots of cli suck because there is no eye.

You could be projecting some. Hard to say. You seem to be making some very strong conclusions which is hard to know if they are correct. Explicit communication is best. But try to start from a more neutral position and don’t assume your feelings/perceptions are accurate to how she feels.

You don’t understand the value of someone red teaming?
