This makes sense. And it would make sense if they implemented this like a regular exchange-style trading halt -- no new positions in shares or options.

However, Robinhood disabled the ability to buy, but not sell.

Why?

It doesn't cost them any money to close the position, so the cash crunch doesn't apply.

Because you can’t prevent people from closing their positions. You can still buy to close a short.

TDA seemed to be preventing GME buys the other day even if you were closing a short call. I wondered if it was intentional or just that nobody thought about the implications of no buys.
