You will find that management consulting firms (and the companies that hire them) have fairly clear rules about how they approach and talk about pricing and competition to avoid the appearance of impropriety. Most notably, they would never ever: 1. Indicate that their advice always is to raise prices 2. They would never share the pricing advice they gave to a competitor.

I don't know if what Patrick does is problematic. It wouldn't surprise me if he was trying to be glib and his actual advice is more nuanced.

If one interprets it literally: Someone who receives advice from him to raise prices can look down Stripe's customer list and find its competition and feel confident that the competition will receive the same advice.

Again, I don't know what he does. All I know is that what he says if read by the right person would be sufficient to trigger their curiosity to ask for records of his correspondence and find out.
