I've been debating a lot in these comments, but I do want to take the time to appreciate this point of view. It's definitely one I hadn't considered.

If Robinhood is getting people who otherwise wouldn't save to invest, even if they're getting worse returns than they would at somewhere like Vanguard, then I could definitely reconsider my perspective that they're a net-evil. I'm not entirely sure I buy that story, but it's absolutely a reasonable perspective and one I'll keep in mind in the future when evaluating new information about Robinhood.
