Marissa was appointed to achieve the near impossible task of turning around a massive behemoth which seemed dead-set on a course towards oblivion. The only key asset that still gave Yahoo significant leverage was its war chest and rather than let it dwindle she decided to invest it in a number of bold steps to achieve a dramatic shift in corporate culture. While some of these steps are indeed turning out to have been mistakes I find I hard to argue, keeping Occam's razor in mind, that her actions did not keep the best interest of the shareholders in mind, especially given Yahoo's performance on the market.
