You're assuming the worst from couple of quotes which aren't clearly one or the other of these statements. From my personal interactions with women in programming (including, btw, the author of one of those quotes), most of them seem to be much more aligned with your "good" argument than the "bad" one. They are concerned that there are lots of women who could be valuable contributors to this community, but who choose to go elsewhere because the culture makes them feel unwelcome and unvalued.
