This article is so on-spot and concisely written. I concur with you, that's an extremely common problem but I suspect hardly anybody recognizes its very existence, much less its impact on communication. When replying to a technical question on a topic we feel knowledgeable about, it's easy to fall for the temptation of showing off without actually thinking whether out contribution is of any actual support
As one often guilty of this crime, this speaks to me like it does to the other commenters.
That said, a distinction must be drawn on whether the asker is looking for an answer or a collaboration. Sometimes they need help getting to an answer and need expertise to work their way there. But if they just need an answer, I'm not sure arming them with nuance is necessarily bad.
Sometimes an end to a conversation just means the need is satisfied. Not that you can fully assume one way or another.
I recognized this phenomenon immediately when I read the piece, and it's something I've never managed (though I've not tried hard) to explain very well before. I am frequently guilty of this exact kind of unproductive attempt to be helpful in my own email communication, though.
