Yeah, and it's a work environment. Contrary to popular belief it's not a single person working on the files, but a hundred. For all we know koko could have been the guest username of a laptop that was temporarily involved in the process. We still don't know who worked on this particular file, who drew the concept art, who imported it, who put the puppets together, and who compiled the file in its current version. Maybe it was on a USB drive that got lost, maybe a laptop that was stolen, maybe someone who gave it to his friend, maybe someone whose friend's friend was in the office and stole it. We don't know who's OP's friend either, hell we don't even know who OP is.
Nobody's getting fired because two drawings of cartoon ponies is on the internet. And /mlp/ won't magically produce the next oscar winning series either, these are just fucking puppets.
What this means however, is that people who already know how to ANIMATE get a chance to create higher quality and more show accurate animations because they get a chance to analyze how the models work. The only thing I'm amazed at is that it took THIS long for something to finally get posted. It's been four years since the show's production started, and all we got so far was a script and a couple storyboard samples.
