I really have to disagree. Dick jokes are perceived to be almost exclusively a part of "guy culture". Want proof? Watch how fast a group of guys making those jokes suddenly clams up and changes the topic the moment an unfamiliar woman walks up. (And when a woman joins in and shows that she's comfortable making those jokes, too, watch how glad everyone is that she can be "just one of the guys".)
So when guys at a conference routinely make dick jokes in public, that contributes to a sense that the conference is a male space. It's not a conscious thing, but it's a real thing, and it would be good for it to change. I don't know that the public shaming in this case was the right way to go about that, but I'm not sure that I have a better alternative to offer, either. (Women are all too aware that quietly saying "Please don't act that way" tends to have no impact at all, apart from the guys thinking she's a humorless busybody.)
