If you look at that graph you will notice the rate of women in CS go from halfway between Math and Engineering to matching the rate in Engineering. I think this is at least in part because as Computer Science matured as a field it became very much like Engineering: a well paying career working in private industry doing technical things. I think this attracted lots of men to the field but failed to attract as many women due in large part to gender roles in our society. That's my long-winded way of saying that CS "moving backwards" is not as accurate as "failing to fix problems that were already there, but not affecting CS as much until it grew up as an industry".
