Since we're in the gaming forum let's stick to the context. From the source you linked:
Just look how Online gaming compares to the other areas on the web. 44% feel men are more welcomed whereas a measly 3% feel women are welcomed. This is just further evidence that the gaming community has a serious gender issue.
Well, it's evidence that the gaming community has a serious perception issue wrt gender. The two don't necessarily track to A=B.
My only major issue with Oliver's segment was that it was long on indictments of the status quo, but rather short on solutions. I thought he was going to talk about the issue of free speech versus threats, the difficulty of attributing anonymous comments, or the questions of how to deal with harassment from a non-LEO standpoint—but it resolved into a rickroll instead.
Obviously making sure the law explicitly covers these sorts of threats and harassment is a good step, but that really doesn't do much on its own.
I don't know whether it's sad or not that I get most of my "news" from John Oliver. For some people it might seem weird that he's making jokes talking about serious issues, but I think mixing comedy with seriousness is great. It points out the absurdity of some of these situations when you can be sarcastic or make non-offensive joke about it.
Maybe it's my low faith in society, but if this was just a regular news segment I don't think most people would grasp how stupid it is that you need to send people naked pictures in order to stop people from seeing your naked pictures.
I definitely think that the blend of humor and news helps highlight issues and get people to pay attention, but it also leads to cheap jokes and dumbing down big issues. I probably don't notice a lot of times since they're discussing stuff I don't know about, but I can see how it could be occasionally frustrating to the people really invested in these causes that their concerns get churned in with jokes.
