They're also a joke because they are, as far as I'm concerned, not a "brokerage". They are an app designed to convince people that they understand how to trade stocks, in order to sell them stocks. A real brokerage should, in my opinion, and some sort of duty to act in the best interest of its clients. A brokerage should not have huge backlash because its users got margin called, and those users didn't even know what…
Getting margin called is one thing. Being prevented from buying a stock is something completely different.
Would you have preferred the alternative where Robinhood risks exploding, has no liquidity, triggers a rush where everyone tries to get their stock out of Robinhood at the same time, fails, and every Robinhood customer is stuck waiting on SPIC for some undetermined amount of time?
Or would you have preferred the alternative where Robinhood didn't allow you to sell either? And then it the stock went down during that time, you can't try to get out?
Robinhood is a shitty company for a lot of reasons, but preventing themselves from being over-extended into bankruptcy isn't really one of those reasons.
