I think they are fine. The way I look at it one just needs to get educated before they become a pattern day trader. Ideally that means they grow their account to $25K and have experience before they are put into a position where they can screw up bad enough that it affects others. Of course people don't do that, but at least there's some incentive. In the end margin is irrelevant if you only trade with money that is actually available. Robinhood is for traders that know even less than the twits on StockTwits. I'm sure it's fine for investing but I'd bet that the vast majority of the people that use the app don't know what the difference is, just like StockTwits.
