Looks like it is just a standard notice of what information they intend to use in court and any names of witnesses they intend to bring. Most likely it's just part of the law firms automation process which files these things in every case after X number of days so that when the attorney shows up without knowing anything about the case, they will at least know that all of the proper documents have already been filed automatically.
Just let it slide off your shoulders and not take up your time. Some people like to judge other people's lives without knowing anything about them. Usually they tend to be former or current debt collectors who enjoy lecturing people around here for "being bad" financially. You notice that this person offered no help with any laws, procedure or facts that led to you winning and improving your situation. They only have a "lesson" for you after the fact. That should really tell you all you need to know.
