> There was a belief, sometimes unstated but often explicit, that no more (serious) discussion is really to be had, and further wondering how can one stop people from asking. It became difficult to discuss anything if there was even something vaguely related asked before.

There is nothing to do with unstated belief here.

It is explicit policy that we don't have discussion at all.

We have answers to questions.

Which is why there's a question (explicitly labelled as such, and not just "help me") at the top of the page, and every post below it is labelled as an answer (and is explicitly not a response to anything else but is simply there to answer the question).
