On the sickness of our community

I assure you a mere employee chosen to be the scapegoat and sate the public's desire for revenge doesn't remain faceless for long. You would probably recognise the face of Francesco Schettino even if you don't live in Italy. Schettino will likely get a jail sentence for his role in the Costa Concordia disaster. But do not be fooled, Schettino while culpable is not the problem, sending this man to jail saves not one single life, it's purely society's retribution.

Firstly let's briefly tackle a purely technical mistake. Brendan was CEO of Mozilla Corporation, not Mozilla Foundation. The corporation is a for-profit, and only its owner the foundation is a non-profit. The corporation hires most of Mozilla's employees and always has undertaken activities that don't contribute to "principles of openness" and of course most of their income is from Google, in exchange for ensuring that the 99% of users who never change their defaults will visit Google's search engine and other properties.

Anyway, so you claim the problem was that Brendan couldn't handle this "PR mess" and this (even though it looks exactly like the others) is not an excuse but instead a /real/ reason why he just had to go.

That seems fine, right? Except, if you fail one component for its inability to pass a new test you made up, it's weird if you then subsequently just never use that test on any other components. That makes it pretty obvious that your real motivation was the failure of that component, not setting a higher standard. So, this new excuse doesn't fly because there was no effort to create a "PR mess" for Chris Beard and see how he'd fare nor for the equally important Mitchell Baker.

In fact Chris and Mitchell can keep their jobs because there isn't a powerful and organised political group trying to get them fired. They probably feel a little bit less secure knowing (from Brendan's experience) that if they piss off the wrong people they're history but for now they are safe.
