I've simply found that this aspect of Swiss culture stands in real opposition to the engineering mindset I rely on in my work as a Software Engineer.
If my (fictional) non-tech-savvy CEO comes up to the engineering department and says "I just came back from %conference% and we need to put everything we have onto the blockchain!", then I will gladly be the one to speak my honest opinion on that rather than publicly agreeing with the CEO, but then ignoring him and continuing with the existing architecture.
Think of it like this: A convention in the USA is to tip service workers, because they are often legally exploitable (by being e.g. paid below minimum wage). So lots of people outside the S would say that "you always need to tip employees, regardless of if they do a good job" is a terrible part of US culture.
I still tip - but I also preferably simply spend my money at establishments that pay their employees living wages and make the concept of tipping extinct completely.
