Well it usually has been when I've personally used it.

There is the disdain of not explaining exactly what you are questioning with the implicit assumption you are questioning everything said. It's pretty much a stand-in for "WTF are you on about? I don't even know how to ask a sensible question about what you said." when I've used it.

In this case though? It's a single statement so maybe a bit abrupt but I read it as a request for clarification. A fairly strong statement was made (essentially "don't use this company") with no backup or explanation. So an equal lack of effort was made proportionally in response.
