Your claim that RH restricted users by choice seems false. RH is required by NSCC/DTCC rules to post collateral for trades in the process of settlement. As a result of volatility, the collateral requirements for meme stocks shot up from something like single digits to something perhaps approaching 100%. Robinhood was apparently forced to draw down a $600MM line of credit just to cover the trades it had already allowed.
