If anything, I think Sundar Pichai will have to face more consequences for botching this launch than firing 12k people in the stupidest way possible.
Boards are a fun thing to have to respond to.
Are you saying that boards shouldn't get upset at botched product launches, especially ones involving tech inflection points?
If the board did do that, Sundar is the directly responsible individual who said "yes". If the board suggests "jump" and Sundar reflexively response "how high?", in my view Google has bigger problems.
Their competitor, whom they’re responding to, is Microsoft, which has been one of the largest companies for much longer than Google has even existed.
