I have worked at a place where people were routinely criticized for asking basic questions on a big all-dev DL (which was archived and searchable, so they actually added to a growing record). The preferred solution was to ask a co-worker on the same team. People were answered a lot of questions were also criticized for being helpful. In neither case was the criticism that much from devs but from managers and given in boss feedback directly to people. Also it had a problem with spreading a good culture and common technical vision to new people, for some reason ( /s )
