That depends a lot on the specifics of the connotations of "signalling" I think. The people who engage in such signalling always have the best of intentions and obviously are only trying to positively influence others, never manipulate them. (Am I insulting them by insinuating that they are unreflective, or being charitable by saying they're not consciously manipulative? Or am I being sarcastic? Does it matter either way? You decide!)
