It is pretty obvious now that quite a bit more than a bunch of redditors short-squeezing a few hedge funds is going on:
My own guesses are that (1) this is just a pump-and-dump scheme with new-tech dressing, or (2) collateral damage for a more complex trade.
Keep in mind also that a "hedge fund" by definition doesn't simply do one trade, like shorting a stock or portfolio of stocks. They do an interconnected set of trades designed to make them money no matter what direction the markets move. To really do that well and consistently (most do not even come close) you usually need to exploit some inefficiency in how the market itself works, and since those inefficiencies change over time your trading strategy would have to change over time as well.
