This is a poor response: Abusive, insulting and makes only a token effort to advance the discussion. Does the fact that it sits at the top of the page mean that it's the most highly rated?

And in practical terms, it seems totally theoretical.

In my experience, more information is always valuable. It's not a matter of shifting responsibility, it's a matter of understanding what the problem is and efficiently getting it resolved.

Sending out an error that is incorrect is wrong -- both a theoretical and practical observation.
