Why should the rudeness of passport control matter if you are "purely" in transit?
I do agree with your sentiment though - in previous years I have generally gotten stamped into Schengen without a word, which now only happens occasionally in the Romance-speaking areas, but at AMS they have seemingly started grilling almost everyone; it's almost as bad as the US
Transits at AMS that involve crossing from Schengen to non-Schengen flights or crossing from non-Schengen to Schengen flights involve passport control.
