IIRC, some people pointed out at the time that this particular trade was quite sophisticated - probably orchestrated by people who knew what they were doing and who understood that the hedge fund they wrecked had acted in a particularly dumb/risky way. I guess with this kind of information, another hedge fund could have pulled that off just as easily as the people from WSB on Reddit.
