aka, RH is between a rock and a hard place - either the clueless user suicides due to poor understanding, and causing bad PR, or they do what they're doing now.
I was a user when they had that suicide situation and RH did do a better job of explaining your actual balance when you entered a somewhat complex trade that caused you to have a negative balance. Still a user, who didn't know what he was doing, entered a complex trade, saw something he didn't understand and ended his life. In response Robinhood could have:
1. Made the UI "easier" to understand (i.e. lie) for 99% of situations
2. Raise the entry requirements to ensure people knew what they were doing (Gatekeep)
They chose (and continue to choose) 1, and I don't envy them - how would ever explain all the ways a margin account can put you in trouble on a 4 inch screen? Most users only care about "instant deposits" and will never get into trouble 99% of time. It took 2 "black swan" events (IIRC, the first suicide issue was during the first COVID market crash) for these issues to come to light.
They brought this onto themselves by optimizing for growth over healthy and sustainable markets.
The marketing push for options by calling it "instant trading" is pretty BS too.
