Here's what's happening right now at companies that don't have an AI acceptable use policy: developers are pasting proprietary code into ChatGPT. Customer support reps are feeding customer emails into AI tools. Marketing is generating content with no review process. Legal doesn't know. Security doesn't know. Nobody knows.
The policy doesn't stop people from using AI. People are going to use AI regardless. The policy gives them guardrails so they use it without burning down the company.
