The difference is that the value of GME isn't in any way connected to its fundamentals here. It is only valuable because of the (supposed) overshorting. Basically, the way I understand it is that everyone is playing poker with tin poker chips. By themselves the poker chips are nearly worthless (tin is cheap), but because suddenly someone owes someone else a whole lot of these chips and there are real green dollars attached to that IOW, the tin chips suddenly are worth a lot. Once that debt is repaid, they become worth only what the tin is worth.

In other words, when the guy that started it all (Roaring Kitty/DFV) testified before congress that the only reason he was buying GME was because he fundamentally thought they were going to be a profitable corporation, that was bullshit. He talks a whole lot about short squeezing the stock elsewhere, so his denial that that's why he did it seems to me to be a lie. On a personal level, he seems shady as hell and the whole thing seems like a setup for others to be left holding the bag.
