If it was significantly socially important I would (hypothetically) but this is not that. I would never betray client confidences or privilege regardless but certain ethical rules prevent me from saying a lot of things that are mostly immaterial to the clients. Most of it is just interesting in the way the sausage gets made. For example even if something is public knowledge I have to pretend I don’t know about it if a client told me about it. More specifically I could never admit I learned about it from the client.
