Increased capital requirements at the DTCC (which I believe you are referring to) were the result of an equation - not due to some discretionary decision.
Overall I think this entire situation is a combination of sketchy abuse of special power (naked short selling and failure to deliver with little/no consequence) and unforeseen side effects (DTCC able to make entire funds, brokers, and exchanges instantly insolvent over night) leading to the Everyman feeling like they have been cheated by the incumbents. I don’t know the correct path forward but I’ve certainly learned more than I’d expected about order flow.
