It's all too easy to judge "those women" and consider them "willing victims" -- whatever that may mean.  
The fact is that these women were victimized.  How can one be a "willing victim"? Yes, probably many moved on in their careers because of that, and they certainly would have been stopped in their tracks if they did not.  For those women, it was a choice to agree and continue their job or career, or sometimes, just go on with their life, or to object and lose a job and be blackballed for years, or, sometimes endure even more harassment.
The person who wields the power is ALWAYS in control.  To place blame on the victim is simply wrong.
