To me it does seem kinda dirty that big billionaire stock groups can basically unify to bankrupt a company and profit from it.
Even before COVID though, I feel like gamestop was legitimately kinda going downhill pretty steadily. Not suddenly, but steadily. People like to buy games online more now, some people prefer buying from amazon instead of the gamestores too, and every time I would go inside a gamestop, only like 2/5ths of the store are games, the rest are weird little plastic doll toy things and knick-knacks that I've never seen anyone actually buy. I don't really get it.
I heard that Gamestop had a recent change of leadership with the CEO or CFO or something like that, and some people thought it would get a kind of boost because of it, but the investment groups thought otherwise, and decided to bet on its bankruptcy (and to my understanding when people try to short sell in the millions/billions, it accelerates this into happening most of the time).
So a bunch of people on some redit group said hey wait, don't you profit form Gamestop's demise! There's still hope! and they all collaborated together to buy the stocks to prevent it from going under. Then the billionaire investment groups decided that the stupid plebs can't mess with them, so they told the stock market trading software being used the most (robinhood) to stop them from being able to participate, and they did. So no Robinhood is being sued, and are pretending to let people participate again (but not really, you can only buy a couple and then you're locked again).
It's really like a rigged game where the old winners who are in cahoots with each other are making new rules in their favor. I haven't heard any news on this for a week or so though, so things may have changed since.
