In short
I think you are.
It is always easy to say: "If you read this or that, you could have avoided this problem", but that goes for pretty much all of the 268,781 (at this very moment) questions on AU.
The problem is, people ask here mostly because they don't know the way to the right sources, and why should we blame them? We've all been there, and moreover, such a comment serves no goal.
Just point out the right way and explain, or link to the right dupe if that is the case.
