I can see how that wording came off as indelicate. Not inaccurate though. Almost every participant has their own style. In individual images this can be hard to see, as the show-style they're tracing overrides that. But when 20 ponies from different people all end up in the same image, it starts to be very, very noticeable. Some characters had thicker outlines, some were over-saturated, some had rounded strokes instead of tapered. In individual images, such things would be of little importance, but all the differences clash in a group image like this. By the time of posting this, there may have been a certain amount of annoyance and desire to never see this poster again.
