Ok, but if they had banned selling and there was a large price drop anyway (forcing investors to eat a loss, unable to sell), they would have been catastrophically screwed legally.
Robinhood doing anything unilaterally about this sounds and feels extremely sketchy and screams illegal to me (if it isn't it should be). It's one thing if the SEC stops all GME trade coz that would be fair across the board. But Robinhood effectively being able to block trades for retail while institutional investors do whatever screams market manipulation.
