I was a little surprised he added that, because<p>1.) post-mortems at Google don&#x27;t blame people, they blame processes, and then they suggest ways those processes could be fixed.<p>2.) I know Marcin personally and I&#x27;ve never known him to blame anyone either.  And indeed, he didn&#x27;t: the takeaway from the article was that the complexity of the web was at fault.<p>My best guess is that he included that because many <i>other</i> organizations who do post-mortems, who he might want to reach with his writing, do think in terms of &quot;Who is to blame?&quot;, and addressing it explicitly may be better than leaving it unanswered.
