As a pretty big contributor to stackoverflow I feel that this is getting blown out of proportion.
I'll usually go extra mile to help someone out but I like my time and the platform to be respected. I often feel that people either expect for their minds to be read or are just bad at explaining there problem. I don't think SO community has to carry the burden of teaching people how to request help - I think it's a skill you earn by trying and failing. Sure your question got closed and someone pointed you to "how to ask a question" FAQ - just reformat your thoughts try again! It hurts nobody.
A lot of other issues like racism, sexism are pretty much unheard of so to me it seems like this article is very much just to pander some recent threads.
