The lesson
Open a position piece with history the reader accepts, then break the deal in plain numbers before announcing what you're changing.
Matthew Prince's letter, dated July 1, 2025, starts with Page and Brin at Stanford and the traffic-for-content deal. It then says AI makes it "750 times more difficult" to get traffic with OpenAI and "30,000 times" with Anthropic. It announces that Cloudflare will "block AI crawlers" by default and closes with "Happy Content Independence Day!"
Don't copy the multipliers or the holiday unless your own claim is as sourced and as specific. Keep the order: shared history, the broken bargain with numbers, then the change you're making and what's next.
