This is _very_ different. They halted _only_ buying, and if I wanted to buy via another brokerage I would need to wait 5 days for funds to clear in Robinhood before I could even withdraw. So they effectively shut off demand but kept supply the same, and there is absolutely no other result that can occur other than the price tanking.
