Respectfully, at this point, do we need Googlers to explain?

Structurally: launch-dependent levels/career advancement. Design wise: massive over reliance on A/B testing. Philosophically: a company hell bent on observing, categorizing, and exploiting us in extremis in exchange for only a tiny "relevant" slice of their potential deliverable.

Because of their focus on "scale", they have never cared about any individual user. The indifference of their technical systems is absolute.
