I don't know if they're right or wrong, but the fact remains there are people who are getting in to both make money as well as stick it to the man.

WSB wants a short squeeze. They got that. But, their theory is that it isn't over, and if they get the 10x+ returns in the coming weeks (I don't think they will, but lets say they do), then these funds are potentially looking at commitments that approach their AUM, and a nasty margin call. That's a real recipe for shutting down, and if that happens, there is no more short to squeeze. Everyone loses.

Someone is paying up.

On the other hand, if they go bankrupt, then their assets are used to compensate (as much as possible) to everyone they owe in cash - not (as previously expected) in that stock. So the expected huge future purchase of the shorted stocks never happens, and all the WSB people who are holding the stock get to keep it or sell it to each other, as all that compensation money does not flow to the market for GME stocks as it would be if the shorts were actually covered. The brokers would be liable, and they might have insurance that might be liable, but all that liability would be cash-denominated and (as far as I understand - if I'm mistaken, please correct me) would not obligate anyone to buy any GME stocks.

The second big difference is in the timing. The current price is driven by short-term expectations, a hope that somebody is going to (or would be forced to) buy large quantities of that stock soon. If one of the shorting hedge funds goes bankrupt, then any settlement for that will take many months, and that money won't influence the market for that time.

The remaining assets the firm has would be liquidated, those would be used to pay off debts, including those owed to the brokerage. I'm not 100% sure how this works, like, if the estate would purchase as many shares owed as possible, or if they would settle in cash with the brokerage, or what. But, regardless, that wouldn't happen until long after the epicenter of this black swan event.
