Nonsense. The hacker ethos is to tinker and learn and there is a very high degree of regard for technical competence. Conversely, incompetence, laziness, especially blatantly so, especially publically is the biggest dick move there is. Wasting other people's metal energy is not nice.

In hacker ethos, you are appreciated for doing your homework and being right; that is very nice. You are a dick when you are lazy, wrong, or wasting people's time and energy.
