It is easy to blame Marissa Mayer for Yahoo’s problems, Katie Benner points out.  But remember that in the seven years  before she took over, six CEO’s tried to turn the company around.  Yahoo has a stake in Alibaba that they will be able to sell in September.  The tax consequences of this sale are difficult to to minimize.  Perhaps structuring a deal in which Alibaba takes over Yahoo would  be the best solution to the company’s problems.   Alibaba’s Ma and Mayer get along.  There would be no reason to for Mayer to step down. And Ma’s brilliance might be used on Yahoo’s behalf.  It’s always easy to blame a woman,  Maybe we should look at the upside here.
