Sure, we can all do some interpreting on their comment which fits our narratives, but that's missing the point.

If they made the exact comment you did, it would've been a good addition to a discussion about the usability of the provided tool. They didn't do that. They just wrote a single short sentence dismissing all of the work of the creator of the application for some reason that wasn't actually explained. Which is why I don't understand that type of comment.
