Don't forget people use ambiguity as a tool all the time.

Politicians use words like "justice" or "freedom" to create common ground with little controversy even when they define the term in a way diametrically opposed to their constituents.

I think it can be the same with "tech debt".

I have a friend who figures when he sells his house it will be a tear-down, so he has all kinds of "house tech debt" that he just manages to live with until he literally moves on. it basically means "I don't care about fixing that" or "I'm not going to fix that ever".
