Meta retired the phrase in 2014. That's the fact. Deductively: a strategy dies when its costs exceed its benefits. Move fast and break things only works when breakage is cheap. Today, a single data breach can trigger fines under GDPR, class actions, and user exodus. The logic is simple: if breaking things invites catastrophic liability, rational actors stop breaking things. My opponent might point to AI, but even there, labs publish safety cards and slow releases. The culture didn't mature; the math changed. The slogan is dead because the incentive to break things is dead.

The practical consequence is this: if move fast and break things were alive, companies would market it. They don't. My opponent's data-center example actually proves my case. To skip permits and rush gas plants, firms must lobby for exemptions, not celebrate breakage. That's regulatory capture wearing a green hat, not a live ethos. Deductively: a norm dies when it can't be stated publicly. When the same behavior requires legal cover, delay tactics, and reputation management, the original slogan is dead. The underlying incentive to cut corners may persist, but the culture that celebrated it is gone.

The other side commits a category error. My claim is narrow: the celebrated norm is dead. Their evidence only shows corner-cutting persists, which nobody denied. Deductively, if a norm were alive, firms would name it. Instead they lobby for exemptions and hide behind regulatory review. That is concealment, not celebration. Corner-cutting is a constant across eras; the slogan's death is the change. Their externalized framing actually concedes this: the behavior had to go underground precisely because public endorsement died. The ethos is gone.
