Can a private support conversation become a public case study?

Extract the general lesson without exposing the private exchange or implying customer endorsement. A public case study that identifies a customer, quotes them or shares their results needs the appropriate permission. Access to an internal conversation is not itself that permission.

If you want a named story, prepare the exact claims, evidence and proposed presentation for review. Keep hypothetical examples clearly hypothetical. The credibility of the lesson should come from accurate reasoning and permitted evidence, not from a borrowed customer identity.
