I suspect it's less a complaint and more a request for someone that knows more to clarify, which often happens in the comments when someone notes they are having a hard time understanding because of missing context. If the first reply was someone explaining the situation, the top level comment would probably have received a bunch of up votes from people that also didn't know instead of down votes from people that now interpreted it as a complaint, because of the context of the initial reply. This is one of the reasons the rules state we're supposed to respond to the best possible interpretation of a comment. Not only is it polite, but it leads to better discussion where we don't devolve into whether a comment was useful, when most comments can be repurposed with replies to become useful regardless of original intent.
