I think the more salient observation is that the author is completely detached from reality. Him writing:

"shoulder to shoulder with incredible engineers, planning ways to make web developers life's easier while raising the quality level of the web."

when Google is primarily responsible for flooding us with ad capitalism and ruining the web, portrays not only a profound ignorance of how corporations work, but a total dissociation from the -very damaging- effects of his work-seen-holistically on the real world. You don't get a free pass working for Google just because you can rationalize your particular niche as "educating users" and "raising the quality level of the web".

Towards the end, it seems to dawn on him that yeah, he "was just a fuckin cog in a mega corp". Let's hope he carries that understanding forward and distills it into a moral and ethical framework that can make the world better.
