I mostly agree, but the only evidence we have is Robinhood's word which industry people seem to have taken as gospel. It's not implausible that they're lying, given that Citadel is their biggest customer, and they could've done what they did without breaking any laws, e.g. by purposely failing to arrange the appropriate credit lines in time, thereby guaranteeing that they'll be able to go "oops, we don't have the capital, we have no choice but to shut her down now".
