This was the exact thought I had. The paper strikes me as being very odd, and the arguments against using 7-segment LEDs are very thin.

I will agree with one thing, though: the right components to use are an engineering decision and as with all engineering decisions, the right choice (i.e., the right set of tradeoffs) needs to be determined on a project-by-project basis. For a given project, that may mean not using a 7-segment LED. Or it might mean that's exactly the right choice.

Could also be a design decision. No reason to let the engineers make all the choices.
