A bit harsh. I think it's more to do with hiring somebody with the right attitude, not just their logbook. An instructor might have better communication skills, it doesn't mean that somebody that didn't instruct is a poor communicator. A pilot who goes bush and does hard yards, might have developed better leadership skills in the process, but an instructor that didn't do that, might have been a natural leader anyway!
The truth is that you need to be both a good communicator and an effective leader when the time, training and seniority call for it.
There is no firm path trodden by anyone to guarantee success or failure in the final outcome.
I think pilot recruitment right now must be harder than ever.
