Agreed. They've adopted the addictive UX patterns of other applications, which is irresponsible for an investment platform. It encourages gambling and making poor trading choices.
Push notifications are a prime example of this. They encourage users to act on short term news rather company fundamentals, which is a dangerous mindset for novice investors. Fortunately for them they've been operating solely during favorable market conditions but when the market does crash I fully expect them to face backlash.
What I would say is that I just don't trust Robinhood as a company. They feel scummy to me, and their marketing and UX pushes practices that I would not consider good investment advice. I can only assume that pushing frequent trading (and poorly-described options trading) on unsophisticated investors makes more money for them. But it's likely at the expense of those investors. Even if I "know better" and could just take advantage of the platform as-is, I don't care to support that behavior.
Take that and pile that on top of -- for example -- their misleading and factually incorrect announcement about their quickly-pulled cash management product last year... yeah, no thanks, I'll pass.
