I remember someone in a recent HN comment thread mentioning that, as an ex-Googler, Google today feels like Microsoft under Ballmer.
So while I agree with you, it _also_ wouldn't surprise me if someone raised the concern, but that person was on a different / more silo'ed team and therefore the concern never reached the execution stage. Herego too many management layers and/or nodes of entropy for communication.
But that's just a hypothesis.
