The advantage of TDT is that it is actually supposed to be a method of choosing how to act. The problem with the metaphor is that CDT and UDT would prescribe the same behaviour in this context.
“I used decision theory to decide.” is not the point of the post, and that does not seem like it would make a very good post. What is actually illustrated is a calculation that can be done to help one decide and intuitively grasp the reason for the decision.

The metaphor still works, but it’s just that it should be about the usefulness of decision theory in general rather than about any particular one.
