Earlier quoted context omitted.
I think there is absolutely no indication that anybody, other than Jesus Christ himself descending from the skies mounted on a Harley Davidson in flames, could have saved Yahoo. So, bashing Marissa here would be really, really pointless and sad.
Why'd she do it then? Got paid a lot, that's for damn sure. $219M over 4 years. http://money.cnn.com/2016/07/25/technology/marissa-mayer-pay...
Remember when she was confirmed as a hire, the feeling around the Valley was less of "wow, a new CEO" and more of "how did someone like Yahoo get someone like Marissa". The previous CEOs include alumni from PayPal and AutoDesk, so getting someone as successful was a win for Yahoo at the time.
