What else could Google do?
Well they could start by telling Yegge, with justification, that a public platform was not the place to begin his criticism - but maybe he had voiced his concerns to his bosses in private, we wouldn't know, would we? Then they could behave like real grown-ups and ask him (and others) to give his views in a reasoned, calm, evidence-based manner, and address the issues he raises. Google can't have got where it is without listening to the clever people it employs.
