I disagree with your argument that antagonistic learning becomes self-destructive. For some, it might, but for those who can deal with it, the lesson that researching a topic before asking about that topic is a valuable one.

Also, no one ever said, "come back when you're a Rails-powered millionaire, and by the way if you're not one already you'll never amount to anything". That's not what's happening above, at all. I agree, if that were the case, that's boring and unhelpful, but that's not at all what happened. That's too specific. The above took place because of the obvious and unnecessary trickery in the submission - people don't like to be taken as fools.
