"but this memo was a mistake and showed poor judgement and more than a little bias"

"openness" and "freedom" are core values of Google. Even in a scenario where someone made effective arguments refuting all of James' key points, a "one strike and you're out" policy seems antithetical to Google's culture. Or any healthy culture for that matter.

If James wrote what you said he did above (I think you mischaracterize him greatly), and if his ideas are as poorly constructed as you suggest they are, surely Google employs someone intelligent enough to go point by point through his memo and really school him. Such a response would do more to build a case for the worldview you appear to espouse than the lazy, generalized retorts being lobbed his way.
