Put aside the scoring and conclusion parts, the author has a couple interesting observations that resonate with me:

> ... but conscientious developers will be interested in doing things right. They’ll spend hours Googling for examples, trying to learn how to type things that TypeScript simply can’t type properly.

> ... if you only need to hire one or two developers, using TypeScript may make your opening more attractive to almost half the candidate pool.

On the other hand, it seems that the author worked on a few medium-size projects and then moved on:

> All projects for which impact was judged were >50k LOC with several collaborators working over several months.

So I wonder if he was able to evaluate the impacts from a longer term perspective, which shall include refactoring experience, iteration speed, developer morale, etc.
