Can you imagine that developer in Yahoo's HR office trying to argue that he or she had no idea how false credentials were added to their resume? ("This must be the work of Anonymous!")
Thompson claims in his note to Yahoo workers that he takes "full responsibility" for the impact his biographical lie is causing the company. No, he doesn't. Not yet, anyway.
Yahoo's perpetually incompetent board wants this to go away because directors fear it will set the company back even further and adversely affect the stock price. It's an understandable concern, but the truth is that Thompson is no visionary. His plan is to cut properties and focus on Yahoo's "core businesses" -- stuff that's been recommended going back to The Peanut Butter Manifesto in 2006. Oh, and he likes to file patent lawsuits.
Yahoo can get plenty of people to do that stuff as CEO. They won't even need a fictional degree in computer science be to be qualified.
And the larger truth is, Yahoo has taken years to become the dysfunctional, unfocused, non-growing mess that it is. How much more damage can a few more months of drift cause?
Unless Yahoo's board thinks rampant cynicism among its employees is some kind of productivity enhancer, it has no choice but to force out Thompson. And the sooner, the better.
