I would have much preferred she change their hiring policies to educate their hiring managers on how NOT to be biased against women and to NOT penalize women who negotiate for themselves. Treat women who aggressively negotiate their own salaries THE SAME WAY YOU WOULD IF IT WERE A MAN! Education, ultimately, is the answer to a long term solution. It would also help to make sure you have an equal balance of sexes that comprise your hiring team to truly level the playing field.
For a capitalist society, if you're a stronger negotiator, then you should absolutely reap those benefits, and if you're a weaker negotiator, then you have something to strive for and improve. By eliminating it altogether, I'm not sure how you can achieve sustainable, long term success. This decision also seems to undermine or belie the accolades thrown on her for being a Feminist icon in the tech/vc world. If you're trying to level the "playing field" then LEVEL it, don't eliminate it.
