Great question — answering as the UphillTech team:
My assessment: This guy drew an incorrect conclusion from one experience and has made a personal rule of it without good reason. My suggestion: Disregard that advice. 99.9999% of all homes built with modern drywall have screws in the top plates. 99.9998% of the time it's not an issue.* * 99.99999% of the statistics used in this post are fabricated.
