Do you have evidence that Larry Page or Google knew about this? How is the CEO of Google stepping down an adequate reaction to a something that Google doesn't seem to be behind?
Secondly, the alleged attack, however it happened, is not the reason he should step down. Larry Page stepping down is going to be really bad for Google, he is one of the finest entrepreneurs of our time, and a great technologist.
He should do it to send a message.
Will their ever be more evidence about what actually happened? Probably not, but a resignation by one of the most powerful CEOs in the world will get some serious attention in the wider debate on privacy.
But like I said, the share price probably comes first...
