There's quirkiness and [whimsy?], and there's needless obfuscation. 'Code Yellow' meaning 'Code Red' is dumb. Like I get it, it probably started as an equivalent to 'Code Wayne' and subverting expectations is funny, but it's a punchline from an old adult swim show more than anything. I get that Google HQ isn't a Hospital or the military, but sometimes clarity is important. More now because they're actively doing contracts for governments and militaries, not a scrappy startup. They became a trusted resource and are now cannibalizing themselves for short term gains.
Whimsy at the top of a company while their workers are protesting their actions isn't great.
