He has a vested interest to talk down the McLaren...

I wouldn't really say that. Just compare the track performance of the 991 Turbo S and the 650S (not even the 570S, which is supposed to be the direct competitor). Keep in mind that McLaren doesn't build a daily driver.

Like other car companies, Porsche engineers get to drive and test competitor products all the time. In the past, the car companies actually bought the cars but recently, I heard there is some sort of official "exchange" of cars. Not sure if this is true but without a doubt, they drive competitor products for comparison. It is part of development.
