Situations occur, and usually customers are receptive if they are given heads up and a reason why. But Robinhood just completely subverted their customer's expectations rapidly and unexpectedly. The entire purpose of their app is TO abstract away the complicated world of stock trading - and they failed to live up to that goal during the GME saga. So I don't get why people are going against the customers whose expectations were set by Robinhood and coming to the defense of Robinhood themselves.
Robinhood offered a product. They clearly showed they can't deliver on the expectation most consumers desire. People vote with their money, and are leaving Robinhood (I cancelled in favor of Fidelity in February 2021). It's fine, it's how capitalism works.
