This is FUD, and saying "This is a confession to a crime, just so you are aware." is really an overly strong statement that is not warranted. Yes, the CFAA is famously lax in what it's definition of "unauthorized access" is, and I know in the past some idiot politicians have tried to prosecute for a journalist clicking "view source" to see the HTML of a webpage, but one shouldn't confuse prosecutorial misconduct for "confessing to a crime". There is nothing in the statement that you are replying to that says that the user actively broke access control.
