There's some other explanations too. Maybe they thought the deception would fly under the radar, so it was rational according to cost-benefit analysis given available information. Maybe they fell for the human psychological bias of overvaluing near-term costs/benefits and undervaluing long-term costs/benefits. Maybe some deception was used internally when the demo was communicated to senior execs. Maybe the ego of being second place to OpenAI was too much and the shame avoidance/prestige seeking kicked in.
