I still have my Ameritrade account from 25 years ago (then Datek, which was, at the time, revolutionary), so I'm not even the obvious consumer of Robinhood services since there was friction for me to stop using Ameritrade and start using Robinhood, but I switched all of my investment activity over to Robinhood a year or so ago (still have some stock at Ameritrade, but I don't actively trade there).
