I don't like this one bit! In many cases, finding the right docs in an org is like finding a needle in a haystack. When someone asks a question that's in the docs, I default to assuming they looked and they couldn't find it, not that they are lazy or trying to put down my work. FWIW with this approach I have not had people needling me like the author here, and I have a ways to go but I have been in this industry for 17 years now.
I think the people that could use more effort in communication will see this post as relatable, and will justify their behavior when interacting with other teams / team members. In my experience infra teams are particularly bad at this, which I attribute to lack of building up a "customer first" muscle that feature teams tend to build by necessity. Of course this is wreckless speculation. I do know that it's annoying when other teams are short with reasonable questions, and have this self righteous attitude that what they work on is obviously perfect and that I'm an idiot for asking these questions!
