I've had my hand luggage both weighed and ignored at Schipol on many occasions over the past few years - you cannot rely on anecdotes here if your goal is to carry extra weight onboard, because there is a good chance you will end up having to pay more (often at a penalty) at check in, or reducing the weight in some other way.
If you fly business class, based on my experience you are more likely to have your carry on ignored so long as its not ridiculous (ie you are visibly struggling to lift it, or it looks like you have packed a small car and put a handle on it to pass it off as carry on).
However, in the current climate, airlines are going to be looking at any cost saving they can take, so I would expect them to be more stringent on baggage weights these days rather than being more lax - the less baggage they carry for your ticket cost, the less it costs them.
